why cant we say magnetic forces instead we say electric forces?
Dear student,
The magnetic field B is defined from the Lorentz law and specifically from the magnetic force on a moving charge:
The implications of this expression include:
1. The force is perpendicular to both the velocity v of the charge q and the magnetic field B.
2. The magnitude of the force is F = qvB sinθ where θ is the angle < 180 degrees between the velocity and the magnetic field. This implies that the magnetic force on a stationary charge or a charge moving parallel to the magnetic field is zero.
