What is the magnitude of the magnetic force per unit length on a wire carrying a current of 8 A making an angle of `30^@` with the direction of a uniform magnetic field of `0*15T`?

Explanation

To find the magnitude of the magnetic force per unit length on a wire carrying a current at an angle to a magnetic field, we can use the formula for the magnetic force on a current-carrying conductor:

### Step 1: Write down the formula for magnetic force
The magnetic force \( F \) on a wire carrying current \( I \) in a magnetic field \( B \) is given by:
\[ F = I \cdot L \cdot B \cdot \sin(\theta) \]
where:
