What is the force on a conductor of length l carrying current 'i' when it is situated in a magnetic field of induction B? When is it maximum?

Explanation

To find the force on a conductor of length \( l \) carrying current \( i \) when it is situated in a magnetic field of induction \( B \), we can follow these steps:

### Step 1: Understand the Force on a Current-Carrying Conductor
The force \( \mathbf{F} \) acting on a straight conductor carrying a current in a magnetic field can be expressed using the formula:
\[ \mathbf{F} = i \mathbf{L} \times \mathbf{B} \]
where:
