WebApr 8, 2024 · The amplitude of the eddy currents produced is reduced as currents cannot flow through the layers of insulator. (Note: OCR B question papers tend to have a question on eddy currents) Questions [edit edit source] 1. A step-down transformer has 300 coils on one coil, and 50 coils on the other. If 30 kV AC is put in, what voltage comes out? 2. WebApr 29, 2024 · E = induced EMF (V) N = number of turns in the coil. Φ = magnetic flux (weber, Wb)t = time (s) The currents generated according to Faraday’s law are known as eddy currents, because they flow, or circulate, in the conductor — similar to eddies in a body of water.The magnitude of eddy current is directly related to the strength of the magnetic … WebDifference between AC and DC Electric current flows in two ways as an alternating current (AC) or direct current (DC).
