Question

If an electron is moving with velocity `vecnu` produces a magnetic field `vec"B"`, then ______.

Options

• the direction of field `vec"B"` will be same as the direction of velocity `vecnu`.

• the direction of field `vec"B"` will be opposite to the direction of velocity `vecnu`.

• the direction of field `vec"B"` will be perpendicular to the direction of velocity `vecnu`.

• the direction of field `vec"B"` does not depend upon direction of velocity `vecnu`.

Answer 1

If an electron is moving with velocity `vecnu` produces a magnetic field `vec"B"`, then the direction of field `vec"B"` will be perpendicular to the direction of velocity `vecnu`.
