Question

The current in the base cylinder increases linearly from zero to 6.2 A in 0.018 s and then drops back to zero linearly in the next 0.036 s. N_B = 2500 turns, N_H = 250 turns, A = 0.85 cm², and ℓ = 0.50 cm.

(a) Find the magnitude of the induced emf in the handle's coil during the first 0.018 s.

b) Find the magnitude of the induced emf in the handle's coil during the next 0.036 s.
