Starting from the expression for the force on a current carrying conductor in a magnetic field, arrive at the expression for Lorentz magnetic force.

Text Solution

Verified by Experts

Force `=Bl = B xx (q)/(t) l But (l)/(t)=v`
`therefore F =Bqv or vec F=q(vec v xx vec B)` - te Lorentz magnetic force.
