Question

Name the factors on which the strength of the magnetic field produced by a current-carrying solenoid depends.

Answer 1

Factors on which the strength of the magnetic field produced by a current-carrying solenoid depends:

(a) Magnetic field depends on current flowing.

(b) Number of turns in the solenoid.

(c) Length of the solenoid

The magnetic field due to the solenoid is:

$B=\frac{\mu Ni}{l}$

Here, $N$ is the number of turns, $i$ is current and $l$ is the length of the solenoid.
