How does a solenoid behave like a magnet? Can you determine the north and south poles of a current–carrying solenoid with the help of a bar magnet? Explain.
Answer
A solenoid is a coil containing many circular turns. These wires are wrapped closely in the shape of a cylinder.
A solenoid behaves like a bar magnet when a current is passed through it.
It’s one end of behaves as Magnetic North Pole and the other end as Magnetic South Pole.
Like in a bar magnet, the field lines emerge from one end and merge into another.
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 solenoid.
- If the magnet is attracted, the end is south end of the solenoid.
If we find the north end, the other end is South. And vice versa
