Question

What is meant by solenoid? How does current carrying solenoid behaves? Give it's main uses?​

Answer 1

✪ Solenoid :

• ↪ A closely wound cylindrical coil of insulated metallic wire.

• ↪ A current carrying solenoid behaves as an electromagnet.

• ↪ The uniform magnetic field inside it may magnetise a steel rod permanently.

• ↪ A coil of many circular turns of insulated copper wire wrapped closely in the shape of a cylinder is called a solenoid.

✪ Current carrying Solenoid :

• » Field lines around a current-carrying solenoid is similar to that produced by a bar magnet.

• » This means that a current carrying solenoid behaves as having north pole and south Pole

• » The strong magnetic field produced inside solenoid can be used to magnetise a piece of magnetic material like soft iron when placed inside the coil.
