Question

What is electromagnetic damping? How is a galvanometer made dead beat?​

Answer 1

Answer: here is the answer Explanation: In a dead beat galvanometer, the coil is wound on a metallic frame. The eddy currents induced in the frame, produce electromagnetic damping. Hence, when the current is passed, the pointer comes to rest immediatly without producing any oscillation of the coil. pls mark me the brainliest

Answer 2

Answer:

Electromagnetic damping induces current to slow down the motion of the object without any actual physical contact with the moving object. When the coil oscillates, eddy currents are set up in a metallic frame, which opposes further oscillations of the coil. This  enables the coil to attain its equilibrium position almost instantly. Since the oscillations of the coil die out instantaneously, the galvanometer is called dead beat galvanometer
