The homopolar motor is the simplest electric motor that uses direct current to power rotational movement. It was first built and demonstrated by Michael Faraday in 1821 at the Royal Institute in London. The name "homopolar" is used because the polarity of the magnetic field emitted by the conductor and the permanent magnets does not change (unlike conventional DC motors).

The resulting rotational movement of the copper conducting wire is caused by the Lorentz force. A conductor (the wire) with a current flowing through it (from the battery) that is placed in a magnetic field (from the magnet) perpendicular to the current experiences a force in the direction perpendicular to both the magnetic field and current. This force provides torque around the axis of rotation and causes the conducting wire to spin.

Put more technically, the Lorentz force is the combination of electric and magnetic force on a point charge. If a particle with charge q moves with velocity v in the presence of electric field E and a magnetic field B, then it will experience the force F = qE + qv x B.

I like the way G+ provided all the #hashtags into G+ null

im surprised that tag #motor did not connect this to the little electric motor that GW built … i though i had thunk that into this space, but apparently i have not tagged it appropriately.  when i get a moment i’ll find it and represent it here … i still have it in my possession and it still works … just have to retrieve it from musty archives.

motors are fascinating in how they keep going with electricity and magnetism and a bit of human contrivance thrown in.

Mark de LA says
use your magic search app null see gw electric motor maybe actually when I typed that into the search gadget at the top of the screen I got just infinite flashing .

Seth says
yeah search needs some work.  i dont think i actually blogged it … but maybe i took a picture once … maybe i put it on facebook … or maybe i found sombody else who had posted that same motor … #IDoNotKnow .

Seth says
i found it →  My First Motor.   I think GW must have assembeled it from a kit becaue i seem to remember seeing it on Facebook and liking it there.   I’ll bet you remember it.
