24. A 50-turn coil has a diameter of 15 cm. The coil is placed in a spatially uniform magnetic field of magnitude 0.50 T so that the face of the coil and the magnetic field are perpendicular. Find the magnitude of the emf induced in the coil if the magnetic field is reduced to zero uniformly in (a) 0.10 s, (b) 1.0 s, and (c) 60 s.

0.1 = 4.42v

1.0 = 0.44v

60 = 7.4 * 10^-3 V

Explanation:

Apply the formula of:

Emf = (No of turns * magnetic flux) : (the given time)

Where your magnetic flux = (0.50 * cross sectional area (pi * 0.075^2))
