Question

what is solenoid . on what factor strength of the magnetic field produced by a current carrying solenoid depend ​

Answer 1

Answer:

Solenoid is a coil of many circular turns of insulated copper wire wrapped closely in the shape of a cylinder

Factors affecting the magnetic field of a solenoid are:

1. The no of turns in a solenoid: Larger the no of turns, greater will be the magnetism produced.

2. The strength of the current: Larger the current passed, stronger will be the magnetic field produced.

3.The nature of the core magnet: The use of soft iron rod as core in a solenoid produces the strongest magnetism
