Question

A current carrying conductor placed in magnetic field experiences a force. The amount of force experienced by a current carrying conductor in magnetic field can be increased by:

• A. Decreasing the magnetic field.
• B. Increasing the current in the conductor.
• C. Increasing the magnetic field.
• D. Decreasing the current in the conductor.

Answer 1

Answer: (B), (C)

The correct options are
B

Increasing the current in the conductor.

C

Increasing the magnetic field.

We know that, force on a current carrying conductor placed in a magnetic field is $F$ = $Bil$. Given, the direction of electric current is perpendicular to the magnetic field.

So, amount of force experienced by a current carrying conductor placed in a magnetic field depends on

(i) the current in the conductor $\left(i\right)$
(ii) the strength of the magnetic field $\left(B\right)$.
(iii) length of the conducting wire $\left(l\right)$.
