please explain
Assume that the magnet has a magnetic moment of μ = 0.6981 A. m². The magnet is moving toward the coil that has N = 488 turns and radius r = 4 cm. a. Find the change in magnetic field of the magnet when the magnet moves from 5 cm to 9 cm from the center of coil. ΔΒ [T] b. What is the induced emf if this change happens in 0.2 s? emf= [V] Đ c. What is the induced current if the resistance of the coil is R = 6? i [A] d. What is the magnitude of ENC? ENC = [V/m] Check
