(B)

direction of the current flowing through it

(C)

radius of solenoid

(D)

material of core of the solenoid

Official answer

The strength of the magnetic field produced by a current-carrying solenoid does not depend upon the direction of the current flowing through it.

Hint

$The direction of the current flowing through the solenoid does not affect the strength of the magnetic field produced.$

Quick oral answer

$The strength of the magnetic field produced by a current-carrying solenoid does not depend on the direction of the current flowing through it.$

Common mistakes

1. $thinking that the direction of current affects the strength of the magnetic field$

Analysis and explanation

The strength of the magnetic field produced by a current-carrying solenoid depends on the number of turns in the solenoid, the radius of the solenoid, and the material of the core of the solenoid. However, it does not depend on the direction of the current flowing through it.

Interesting facts

$The strength of the magnetic field produced by a solenoid can be increased by increasing the number of turns in the solenoid or by using a ferromagnetic core.$
