If an electron is moving with velocity \(\vec{v}\) produces a magnetic field \(\vec{B}\), then:
1
the direction of field \(\vec{B}\) will be the same as the direction of velocity \(\vec{v}\).
2
the direction of field \(\vec{B}\) will be opposite to the direction of velocity \(\vec{v}\).
3
the direction of field \(\vec{B}\) will be perpendicular to the direction of velocity \(\vec{v}\).
4
the direction of field \(\vec{B}\) does not depend upon the direction of velocity \(\vec{B}\).
