Homework Statement
Eliza connects a power supply, switch, and a multimeter (in ammeter mode) in series with a wire coil. The wire coil is held into place by 2 connecting wire leads. One of the wire leads has been stripped off of the insulating enamel coating so that half the wire is bare; the other lead has been completely stripped bare.
1. What orientations of the coil will give a current through it due to the battery?
2. During the time that there is a current through the coil, which side of the coil will act like a north pole and which side will act like a south pole? Explain?
3. How will the coil behave when placed above the magnet and the switch is closed?
Homework Equations
Faraday's Law: E=-d(magnetic flux)/dt
Magnetic Flux = B*Acos([tex]\theta[/tex]
The Attempt at a Solution
The part without coating will give a current, but the part that has coating will not?
Very lost...
