What is the magnetic force formula or write down the mathematical expression for magnetic force:
The cross product or vector representation of the velocity v of the particle and the magnetic field B gives the magnitude of the magnetic force is given in the vector form and the relation is F=q[v✖B]. Also, the cross product can be replaced with sinθ and the expression is written as F=qvBsinθ, where θ denotes the angle between the velocity component and the magnetic field component. And this θ is found to be less than 180 degrees.
