so glad I could learn more about motors
Love the dancing robot. I’m going to save my points to get one. Alexa answer me when I am not talking to her to as well.
Electricity is cool to me, because I love lighting!
Electricity is so fascinating!
I have always loved electric motors but this was awsome.
It is cool how much goes into making motors
I love area 51 because I always learn something new. love these videos.
We just bought an electric riding mower. It is so quiet
Robots are very cool!
I vote for ACD2 AND YES I WANT BIG MOUTH ON ACELLUS STORE!! R51 IS SOO FUNNY😂😂
I love motors I’m so glad I could learn more about them
Motors and fascination goes a long way in our heart. The technologies and inventions stories are very inspiring.
I love motors
so that’s how they work.
Whoa! I’ve always wanted to know how electric motor works! it would be so cool to be able to do that at home!
Wow, this is very cool. I always wanted to see how motors work
Electric motors are so awesome and how they are in so many things that we use today is so fascinating that is the reason why we can travel easier than ever before cars, trucks, planes, and, bikes all are part of this fast-traveling system.
It is pretty crazy how much goes into making electric motors work.
I’ve always thought magnets and energy were interesting
My favorite episode so far
I didn’t know it worked that way, amazing!
The story with faraday and the electric motor was very interesting.
I didn’t know magnets could power electric motors.
how are electricity and magnets connected?
Never knew how they work! Thank You!
So that’s how they do it
Wow this episode was really interesting
Amazing!
It’s so fascinating how magnets power electric motors!
I learned that there is motors in dancing robots.
I learned in a electric motor there is a magnets a South Pole and a North Pole.
My dad would let me expeimermet with his drill. The cartoon Roger Billings is so funny.
Cool!!!! I would love to learn to make a real motor. I made a lego pull and go car with my brother.
Love you guys
Motors help stuff move and operate this means that learning more about motors can really come in handy.
This is shocking…
Very interesting.
Did Roger Billing built a motors.
cool
Awesome Possum!!!
I never knew we used screws to make magnets
I made my own electric motor before. Also I have a question wouldn’t the copper wires in the motor (since they are touching ) wouldn’t that lead to a burn?
robots are so cute!!
cool
I like electric motors.
I liked learning about what makes electric motors work.
The robots are so adorable!
I love the dancing robots!!!
now i want to also see if i can make a magnet
Malachi finally learned Italian and it was for nothing😢
Constant motion is achieved by reversing the polarity of the rotor magnet just as it finishes flipping into place. Doing this means that each pole of the rotor magnet is now attracted to the other pole of the field magnet, so it flips again. Then you reverse the polarity again and so on.
luckily I like raspberry pie
but AC-D2 is amazing
the other one is clumsy
my vote is little
This episode was very interesting 🧐, and its crazy how that little magnet was able to pic up a big tool! very fastenating!!
I never knew that people used screws and wires to make a magnet.
It is cool that you can make a magnet out of wire and a screw!
This is so cool! I never would’ve know that motors required magnets.
This is so cool! I never thought I’d learn how electric motors work.
I’d love to learn about how differing power sources (like solar energy) come into play here, since the coils need a charge to pass through them to become magnetized.
is this what makes an EV?
I need to understand this.
Electric motors are a step in the right direction.
funnnn!!!!
haha cool!!
i love motors especially working on them
very cool
I have a STEM motor kit and it’s so fun
wow!
Motors are so interesting
Awsome!
little acd2
That’s so cool I didn’t know that 😀
The robots participating in a dance competition was so fun I loved it!
Woah that’s cool
Wow cool
These motors are awsome!
the story of faraday discovering the movement of electric motor and the battery was extremely interesting and captivating
These motors are so cool!
Wow! Thanks
cool
This is a really great video!!
Cool
cooll 😍
Motors are definitely super cool and interesting!!
Love this video
Confusion on electric cars so I know that teslas do it but when the motor gets extremely hot the motor catches fire and you cant put it out and another question when the cars are completely charged they only last so long so what do you do when the car quits and does the battery freeze when it is in the winter?????????
are magnets and electric motors related in there energy?
More of a question than a comment, but what was the first thing that electric motors impacted?
This is one of my favorite episodes.
What is the nest way to conserve power.
Thank you!! That’s awesome!
Yes kit! I would love to make my own motor at home. I love hands on activities.
I want to learn to code! The robots dancing is funny!
very interesting video
THAT IS AWASOME
I love how motors work
Great video! I think the dance-off should be a tie.
My dad works on motors and say electronic ones are no good and we should stick with good old gas motors!
I vote the monster spider creature and the guys that did the dance.
Russell Mattsson my grandpa has a tesla ,they are very cool
love this!
I love it
Interesting video I love the idea of electric motors.
It is always fun to learn new things about motors

yes kit
WOW
Loved watching this episode and it was really interesting learning about dc motors.
That’s awesome!!! Yes kit
cool
I vote big, because that cranberry pi-bot becauuse even though it has more akward bot moments but it is also a better dancer.
very interesting how the magnet electric machine works! I wonder if that’s how some other machines are built.
What are some other things Michael Faraday has done?
this is so cool
Very interesting
I cant wait to learn more about motors!
The spider-like thing was so cool!
yes kit
I’ve always wondered how motors worked they are in so many things.
The little robot can do ballet!!!
I like this one!
Very informative! 👍
it’s crazy to think about all of the difrent was that we can make magnets.
I did not realize until this episode that magnets could be turned on and off.
I love this
This will go amazing with my science studies.
Thank you for the tips for getting better grades. It helped me a lot more than you think. I vote for the spider like robot to win.

nice!
Wow
Wow!
motors are awesome
this was such an interesting lesson!
I want to make my own scooter with an electric motor
what’s electrolysis?
Which has a longer longevity electric or traditional motors? What everyday technology do we use that also uses magnets?
HAPPY THANKSGIVING!!!!!!!!!!!
so cool
evolution of anything is so cool to see! Imagine if some of the motor’s leading pioneers got to see where motors have gone today.
this is so cool
the dancing robots are hilarious
Great lesson, electric motors are a great invention.
Just like Max, I live in Virginia too. It is so cool that Acellus students are all over the world!
What motor kits will we have?
This was a really interesting video. Thanks!
Amazing! R-51 is very entertaining 😀
Wow! Cool to learn about electric motors.
very interesting
Thats an interesting fact that notes help you study better, because I use the Google Docs on my computer to take notes for my Acellus subjects.
WOW
The little robot can do ballet! That one is my favorite.
fun!!!
thank you for teach us how to make electric motor works.
👍
I thought it was very cool when you showed how to build an electromagnet.
I understand how they work and this was a great video.
Checking in.
What was the IQ of the inventor of the inventor who made the first one? Did he go to school?
“all of us celebrities will be moving to canada” lmao
Thank you for the information. 🙂
such a cool subject
sounds interesting
Learning about how electric motors work is interesting.
I’ve always been fascinated by how electric motors work, but never fully understood them. Now thanks to Dr. B I understand them fully and now know who to make simple ones. So thank you very much for this awesome video!!!
how does the motor tell everything else to move?
Yes kit please
I like motors
what is the difference between electroic motors and regular motors, and which is more effective?
This was excellent at teaching how electric motors work! We need this to start engines, power fans, and do more daily life things!
I find all of these videos interesting
People that take notes score higher then people who don’t take notes. The people that take notes score about 13% higher
for the others out there take notes it will help you get through life
what are the key components that make an electric motor work.
I always wondered about motors. It’s so cool that it can send signals. science is the best. Who agrees👍🏻 reply.
i love electric motors
It is so cool on how electric motors work! You guys are awesome for letting us kids know this stuff!
Mr. Tobias is cool!
wow soo cool i like this epoisod and i was the first to do a comment ;]
I love what makes motors work
I like motors and love how they work
amazing science live keep up the good work guys
did u find the mars meteor
i thought it was cool when they need electricity to work a compass.
Nice video, really fascinated by the electric motor system and the ways it can be used.
Excellent video! Electric cars seem like a good way to reduce our dependence on gas and save money on gas. It’s just that my thing about electric cars is that when the Electricity turns off, what will charge your car?
I loved this episode
Interesting
Right that it is totally fair for R-51 to have a video intro? I mean, everyone else has one and R-51 is also part of Science Live.
This was a great session and I enjoyed it.
I vote for AC-D2
Thank you science live and the teachers
science is soooooo amazing
A moter is in a fan?
I liked the spider-like mechanism. It looks very advanced and efficient.
So cool!!!! I love this website. Acellus changed my life so much!!!
The segment on getting better grades really helps.
Motors are cool! For some reason, my comments never work when it is put in watch now.
What about pulse modification radio (pm)?
O my goodness R-51 nearly made me die from laughter!!!!!! I WANT A BIG MOUTH!!!(A toy one, not a real one lol) Also I think that the motor kits are a really good idea. I voted for the spider-like robot.
Can you magnetize every metal?
From Max Rovira in Virginia
Wow!
