Why force is directly proportional to sin theta in magnetism
As we know Magnetic force is given by,
F = q(v×B)
As F is directly proportional to cross product of the velocity v and Magnetic field B.
As we know,cross product (v×B) = vB sinθ
where θ is the angle between v and B.
So F = qvB sinθ
F = q(v×B)
As F is directly proportional to cross product of the velocity v and Magnetic field B.
As we know,cross product (v×B) = vB sinθ
where θ is the angle between v and B.
So F = qvB sinθ
