Question

The strength of each of magnet reduces to half when it cut along its length into the equal parts magnetic field strength of a solenoid. Polarity of solenoid can be determined by *​

Answer 1

Answer:

A solenoid behaves like a bar magnet when a current is passed through it. ... Yes, the north and south poles of a current–carrying solenoid can be determined with the help of a bar magnet. We can bring the North of a Bar Magnet towards one end of the solenoid. If the magnet is repelled, the end is north end of the soleno
