Answer:
1. When a nail is kept close to a magnet, the magnetic field from the magnet turns the nail into a temporary magnet with two opposing poles. This is the reason why the nail is able to attract pins in the presence of a magnet.
2.Magnets attract paper clips because magnets have a magnetic field, which creates a force, that pulls on other ferromagnetic materials. A paper clip is usually made of steel wire. ... Iron is a ferromagnetic material that is attracted by magnets.
3.The number of pins attracted to the soft iron rod increases as the number of turns of the coil is increased. When the current is switched off, the pins dropped back into the Petri dish because the soft iron rod cannot retain its magnetism.
