Question

Under which condition, an electron moving through a magnetic field experiences maximum force?

Answer 1

When a charge passes through a magnetic field,it experiences a force called Lorentz force.

$F=qVB\sin \theta$

For F to be maximum.

$\theta =90°$

$⟹F=qVB$

For electron

$q=e$

$⟹F=eVB$

Maximum when travel in perpendicular direction to $\overrightarrow{B}$
