Question

What is the difference in behaviour of a solenoid and magnetic dipole?

Answer 1

Answer:

Solenoid is comprised of a conducting rod with turns of a wire all over its length and when electricity is passed through that wire the core or that rod gets magnetised making this setup a strong magnet and as its due to electricity, its rightly called an electromagnet. It behaves like a magnet only till electricity is kept flowing otherwise it loses its magnetism hence it is also called a temporary magnet also. Bar magnet is a natural magnet and it behaves as such without any external influence. Its magnetic field or the area in which its magnetism can be observed is quite small compared to a solenoid which is a stronger magnet.
