AI Generated Solution

To understand why the oscillating coil in a galvanometer with a fixed core made of non-magnetic metallic material comes to rest quickly, we can break down the explanation into a series of steps: ### Step-by-Step Solution: 1. **Understanding the Galvanometer**: A galvanometer is an instrument used to detect and measure small electric currents. It consists of a coil of wire that can rotate in a magnetic field. 2. **Coil Oscillation**: When an electric current passes through the coil, it generates a magnetic field which interacts with the magnetic field of the galvanometer, causing the coil to oscillate. ...
