Observation of the formation of these phenomena is the general goal of nondestructive testing of ferrous compounds using MPI. In quasi-static conditions, the power dissipation due to these phenomena is inversely proportional to a constant that is 1 for a sheet and 2 for a wire. Waste sorting at recycling facilities use these phenomena to separate metallic materials. In transformers, power loss caused by these phenomena can be minimized using laminated conductors and ferrite cores. Generation of these phenomena is used in braking systems often employed by roller coasters. These phenomena form due to a magnetic response as a consequence of Lenz’s law. For 10 points, what phenomena consist of electric charges moving in closed loops during induction, named for their resemblance to whirlpools? ■END■
