**Dopje rolled a random image posted in comment #110 at Ultimate villain ** its magnets and a battery, that makes a electric motor, ooh yeah science baby

TwoHalves (05/12/2013) [-] The little metal balls are magnets; they are creating a directionalized magnetic field.
The battery passes a current through the wire, which is looped in the center. This is called an induction coil; it causes an electric field to flow through the loop.
Because this field will always be perpendicular to the magnetic field, the loop experiences a torque due to what's commonly known as the Right Hand Rule (masturbation pun here). This is what causes the wire to spin.
This is an extremely basic example of an electric motor.

The Lorenz force produces the torque I think. RHR is also known as physicist yoga.

Just a note, the Right Hand Rule is a generic convention of establishing a coordinate system and is used in many other situations outside of electricity and magnetism.
The loop is experiencing a torque according to Faraday's Law of Induction which says that the electromotive force (the force causing the rotation) is equal to the number of turns in the wire times the change in magnetic flux (which is caused by the current flowing through the wire).

chaoscustoms (05/12/2013) [-] I have 3 questions\
What is this?
Where can I get one?
How much will it cost me?

greatgatsby (05/12/2013) [-] I've studied for my physics final too long...
I just solved why this works

changing current in a static B field causes a fore perpendicular to the flow of the current which in turn produces a torque on the ring of wire and causes it to spin. you can use the right hand rule to actually find which way the current is flowing too, if the motion was slow enough.
i also just had a physics final lol

bakerboytom (05/12/2013) [-] ok guys which way is the current flowing?
physics student reaction: thats a homopolar motor! i can use my knowledge of electromagnetism to work out current flow direction using flemings left hand rule!
everyone else: look at the big + sign on the battery

Greevon (05/12/2013) [-] We just got done making DC motors in physics class. It was a damned pain in the ass because mine would just twitch back and forth like an epileptic monkey and then die.

arcanesyrge ONLINE (05/12/2013) [-] You used DC on a slip ring motor? or a dead battery.

planetpluto (05/12/2013) [-] It was dc. You need the electrons flowing one way in this type of motor.
