Question

An electron is moving parallel to a uniform magnetic field with a constant velocity. What will be the path of the electron?

Professor PC Thomas Classes · Answer

Magnetic force is $F = qvB \sin	heta$. Since the electron moves parallel to the field, $	heta = 0^\circ$ and $F = 0$. Thus, it continues to move in a straight line with constant velocity.
