Answer:
why nail is attracted towards pin?
Because 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
Answer:
It is the principle of electromagnetism.
The battery provides an electric charge to the metal core via the wire. It has the structure of a solenoid, thus has parallel field lines inside the metal core and field lines outside and surrounding the electromagnet have the same pattern as a bar magnet. Since it is an electromagnet, it attracts the metallic clips to it
In short it behaves as a bar magnet.
The core gets a temporary electric charge from the battery and attracts the clips
As soon as the power is cut off from the battery, pins will no longer be attracted to it
