What is the magnitude of magnetic force ...

What is the magnitude 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?

Text Solution

Verified by Experts

According to Ampere.s law,
`F=IlBsintheta`
`thereforeF/l=IBsintheta`
`thereforeF/l=(8)(0.15)sin30^(@)`
`thereforeF/l=0.6Nm^(-1)`
