A square copper plate of side 10 cm lies perpendicular to a uniform magnetic field that is increasing at the steady rate of 0.20 T s⁻¹. If the effective resistance for the circulating eddy current path inside the plate is 0.020 Ω, estimate the magnitude of the eddy current set up in the plate. How will this current change if the plate thickness is doubled, assuming the resistance halves while all other conditions remain the same?
