Electrostatics

Electrostatics Magnetostatics Electromagnetism is the branch of science that deals with the phenomena arising from stationary or slow-moving electric charges. Magnetostatics is the study of static magnetic fields. In electrostatics, the charges are stationary, whereas here, the currents are steady or dc(direct current). Electromagnetism is the physics of the electromagnetic field, a field that exerts a force on charged particles and is affected by the presence and motion of such particles.
