  • so magnets make electricity...never thought about that

  • if you notice how the south pole is attracted to the south pole and vice versa for the north poles... isnt this incorrect? since like repulses like and opposites attract...

see all

  • @Aasmaema That is why you need the driving physical force of the generator, otherwise it would move all by itself and violate several laws of motion and conservation of energy.

  • @Aasmaema a magnets poles are only named as such because of the way the point in the earths magnetic field, if you imagine the earth has a giant bar magnet inside the north pole of said magnet would be at the earths south pole! people really need to name things better in science lol

  • I hate 240p. Why cant we like just ban 240p?

  • @Aasmaema

    I think the video is correct. The magnetic attraction between the N and S, and the magnetic opposition between N ans N or S and S, both create the induced magnetic field. You need the change from this "second" magnetic field in order to produce current within the armature. So the applied magnetic field depends on it to produce current.

  • 240p...we meet again...

  • poor joseph henry...

  • Walnut

  • At 8.00 picture there's a thing I don't understand:

    Is there a physical contact between the spinning bar and the conductor? If so,isn't that contact prone to be damaged as a result of the continuous spinning?

  • Was this filmed with a female gooch?

  • Proton-enhanced nuclear induction spectroscopy

    P.E.N.I.S.
