WebEddy currents are current loops formed over conductor surfaces due to changing magnetic flux. They are useful in induction heating, levitating, electromagnetic damping, and … WebEddy currents can produce significant drag, called magnetic damping, on the motion involved.Consider the apparatus shown in Figure 10.5.1, which swings a pendulum bob between the poles of a strong magnet.(This is another favorite physics demonstration.) If the bob is metal, significant drag acts on the bob as it enters and leaves the field, quickly …
