These phenomena are the primary cause of the skin effect when an alternating current passes through a conductor. For 10 points each:
[10m] Name these phenomena that induction stoves use to create a heating effect. Lamination is used to minimize the effect of these phenomena in transformers.
ANSWER: eddy currents [or eddies; accept Foucault currents; prompt on current]
[10h] Another method for reducing losses in transformers caused by eddy currents is to use these wires, which are made of many thin wire strands woven together. These wires also reduce losses due to the proximity effect.
ANSWER: litz wires
[10e] Eddy currents are governed by this English physicist’s namesake law of electromagnetic induction, which has a minus sign because of Lenz’s law.
ANSWER: Michael Faraday [accept Faraday’s law of electromagnetic induction]
