CBSE · Class 12 · Physics · Moving Charges and MagnetismThe magnetic force on a moving charge $q$ moving with velocity $v$ in a magnetic field $B$ is given by:
Step-by-Step Solution
The magnetic force vector on a moving charge is given by the Lorentz magnetic force formula: $\vec{F} = q(\vec{v} \times \vec{B})$, which in magnitude is $F = qvB\sin\theta$.
