Hi there,

Moving electric charge produces magnetic field. In other words magnetic field is created when an electrical charge in motion.

Most basic form of force is that which magnetic field exerts on moving charges. Direction of magnetic force on moving charge  follows right hand rule and it is perpendicular to plane formed by V and B.

Magnitide of force is proportional  to q,v,b and the sine angle between v and b .

Hope it helps you

Good luck!
