What is the magnanitude of magnetic force per unit length on a wire carrying a current of 8 A and making an angle of `30^(@)` with the direction of a uniform magnetic field of 0.15 T ?

Explanation

I =8A, `theta = 30^@`, B = 0.15 T
`F= Bl // sin theta`
`F/l = BI sin theta = 0.15 xx 8 xx sin 30 = 0.6 Nm^(-1)`
