A magnetic field is changing at a rate of 0.02 T/s in a coil of wire with 200 turns. What is the induced emf in the coil?
The induced emf can be calculated using Faraday's law:
induced emf = -N x (ΔΦ/Δt)
where N is the number of turns, ΔΦ is the change in magnetic flux, and Δt is the change in time.
Given: N = 200 turns, ΔΦ/Δt = 0.02 T/s
induced emf = -200 x 0.02 = -4 V
