Electromagnetism

While light, magnetism, and electricity behave differently and were long thought to be entirely separate studies, they are now known to be interrelated. The divisions of the subject are optics, magnetism, electric current, and electrostatics.

   

Optics

Optics includes areas of the electromagnetic spectrum, physical optics, geometric optics, and electromagnetic waves.

Magnetism

Magnetism includes magnetic properties of matter, magnetic fields, magnetic force, electric current assemblies, and electric current elements.

Electric Current

Electric current includes areas of alternating current circuits, direct current circuits, resistance, EMF, and current definition.

Electrostatics

Electrostatics includes areas of electric properties of matter, capacitance, electric flux, electric potential, electric field, electric force, distributions of charge, and electric charge.
