Practicing Success
If an electron is moving with velocity v produces a magnetic field B, then; |
Direction of B and V are same The direction of B is opposite to V The direction of V is perpendicular to B Direction of B is independent of V |
The direction of V is perpendicular to B |
According to Biot-Savart's law, The direction of B will be along Vxr i.e. perpendicular to the plane containing V and r |
