Transcribed Image Text:3. The N and S pole faces of a bent cylinder magnet form are separated
from one another by a small gap, forming the magnetic analogue of a parallel
plate capacitor. Positive magnetic charge is uniformly distributed on the north
pole face and negative magnetic charge is uniformly distributed on the south
pole face. If the magnetic field B in the gap is 0.2 Tesla, what is the magnetic
surface charge density on each of the two pole faces? If the radius of the pole
faces is 4.0 cm, what is the force of attraction between them?
