A straight conductor of length L and carrying a current I is kept in a uniform magnetic field of induction `vec B`. Write the expressions for the force on the conductor and the magnitude of the maximum force.

Text Solution

Verified by Experts

The force on the current - carrying conductor is
` vecF = vec(IL) xx vecB`
where vecL is in the direction of the current.
` |vecF| = ILB sin theta`
` :. |vecF_("max")| = ILB`
when the angle ` theta` between `vecL and vecB " is " 90^(@)`.
