Question

What Lorentz force does each free electron in the moving rod experience when \[\vec{v}\perp\vec{B}\]?

Options

• \[F=qvB\]

• \[F=vB/q\]

• \[F=qv/B\]

• \[F=qlB\]

Answer 1

For velocity perpendicular to the magnetic field, the force magnitude is \[F=qvB\]. This Lorentz force acts on free electrons in the moving rod.
