What is eddy current explain any four application of eddy current?
Important Questions on Electromagnetic Induction
Vandana was a student of Class 12th Science. She went to visit a science centre with her friends. There, she saw a magnet oscillating through a string. She observed that oscillation stops when a metal plate is kept under the oscillating magnet. She could not understand the reason. She discussed with her friends that oscillation will continue or stop when the magnet is kept under the oscillating metal plate. The next day, they went to their science teacher and became happy to know the reason for the phenomenon.
Why oscillation stops when a metal plate is kept under the oscillating magnet? Give suitable reason.
Spherical insulating ball and a spherical metallic ball of same size and mass are dropped from the same height. Choose the correct statement out of the following {Assume negligible air friction}
