Question:
A proton travels through uniform magnetic and electric fields. The magnetic field is B = 2.50imT. At one instant the velocity of the proton is v = 2000j m/s. At that instant and in unit vector notation, what is the net force acting on the proton if the electric field is?
(a) 4.00k V/m,
(b) -4.00k V/m, and
(c) 4.00i V/m?

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. The video shows the practical implications of magnetic force around different objects.
