Question

what is soleniod? how does a solenoid behave like a magnet? can you determined the north and south pole of a current carrying solenoid with a help of bar magnet? explain

Answer 1

heyaaa!!!! here you go..... ❤️❤️❤️❤️❤️❤️.....

#solenoid:- a solenoid is a long coil shaped object which has large number of turns of insulated copper wire.

a solenoid behave as a magnet when current is allowed to pass freely from the insulated copper wire as we know moving current creates a magnetic field around it and thus the magnetic field produced by solenoid is high due to large number of turns.

yes we can determine the North and South Pole of a solenoid by a bar magnet we can do this by following:
take the north pole of a bar magnet and bring it near one end of solenoid if the end repels the bar magnet it will be north pole of solenoid and if it attracts the north pole of bar magnet it will be South Pole of solenoid.
