A source injects an electron of speed v = 15 x 107 m/s into a uniform magnetic
Question:
A source injects an electron of speed v = 15 x 107 m/s into a uniform magnetic field of magnitude B = 1.0 x 10-3 T. The velocity of the electron makes an angle θ = 10° with the direction of the magnetic field. Find the distance d from the point of injection at which the electron next crosses the field line that passes through the injection point.

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.
