1. Is it possible to orient a current loop in a uniform magnetic field such that the loop will not tend to rotate?
2. Will a nail be attracted to either pole of a magnet? Explain what is happening inside the nail when it is placed near the magnet.
3. A wire carries a current of 10.0 A in a direction that makes an angle of 30.0° with the direction of a magnetic field of strength 0.300 T. Find the magnetic force on a 5.00-m length of the wire.
