• Electrostatics
is the branch of science that deals with the
phenomena arising from stationary or slowmoving 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.
