Write the expression, in vector form, for the Lorentz magnetic force `vec(F)` due to a charge moving with velocity `vec(v)` in a magnetic field `vec(B)`. What is the direction of the magnetic force ?

Text Solution

Verified by Experts

`vec(F)=q(vec(v) xx vec(B))`
Perpendicular to the plane formed by `vec(v)` and `vec(B)//, vec(F) _|_ vec(v)` and `vec(F) _|_ vec(B)`.
