What is the magnitude and direction of force on an electron moving along the direction of the magnetic field.

Text Solution

Verified by Experts

When an electron is moving along the direction of the magnetic field, then angle `theta` between velocity vector `vecv` and magnetic field `vecB` is zero degree, i.e., `theta=0^@`. Lorentz magnetic force
`F=-evBsin0^@=0`.
