1.	The bob of a simple pendulim is replaced by a magnet. The oscillations are set along the length of the magnet. A copper coil is added so that one pole of the magnet passes in and out of coil. The coil is sort-circuited. Then which one of the following happens?A. Period decreasesB. Period does not changeC. Oscillations are dampedD. Amplitide increases
Answer» Correct Answer - C It is due to the magnetic field produced by coil.
