Answer:
1.The part that we call the nail is technically known as the “nail plate.” The nail plate is mostly made of a hard substance called keratin.
2.battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit.
3.If you disconnect the wire, the magnetic field disappears and the nail is no longer a magnet. If you leave the wire connected long enough, the nail's magnetic domains will realign enough to make it a permanent magnet.
4.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.
