When a current carrying conductor is placed in a magnetic field, the moving charges experience a force.
That force is-
1. Proportional to the magnitude of magnetic field, F∝ B
2. The force is proportional to the charge, F ∝ q
3. The force is proportional to the component of the velocity v in the perpendicular direction of the field, F ∝ vsinθ
So, F= qvBsinθ
