Question:
An electron with kinetic energy 2.5keV moving along the positive direction of an x axis enters a region in which a uniform electric field of magnitude 10 kV/m is in the negative direction of the y axis. A uniform magnetic field B is to be set up to keeps the electron moving along the x axis, and the direction of B is to be chosen to minimize the required magnitude of B. In unit-vector notation, what B should be set up?

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.
