A 860 turn coil is wound around an open rectangular cylinder just large enough that a bar magnet will fit
inside the coil. When the magnet is dropped into the coil in a time of 0.48 s, an emf of 0.50 V is induced. If
the cross-sectional area of the magnet (and the coil) is 4.0 cm²: ( These units need to be converted.)
a) What is the value of the magnetic field B of the bar magnet? Note: 1 T = 1 Vs/m².
b) If the N pole of the magnet is dropped down, which direction is the induced current to an observer
on the N pole of the magnet (a clockwise or a counter-clockwise induced current)?
