Magnetic Field of a Moving Charge, Proton, Right Hand Rule – Physics & Electromagnetism

This physics video tutorial explains how to calculate the magnetic field of a moving charge such as a proton. It explains how to determine the direction of the magnetic field of a moving proton using the right hand rule and the i j k technique. You need to find the cross product of the velocity and position vectors.
