Magnetism is a physical phenomena that is part of our everyday lives.  The study of electromagnetic theory combines the interrelated effects of both electricity and magnetism and focuses on the many ways that magnetic fields and electrical current and electrical charge are related.

The following video by the PBS provides a crash course in a few of  the fundamentals of electromagnetic theory at a level usually taught in a high school physics course:

Magnetism: Crash Course Physics #32

In our macro, everyday world, the most common ways to encounter magnetic force are to move two magnets near each other or move ferromagnetic materials near a magnetized object.  The other common way to encounter magnetism is to experience the resulting magnetic field generated by current moving through a conductor.  

The force you can experience from the magnetic field generated by a current flowing through a wire is given as:

`F = I * l * B * sin theta`

See the textbook chapter on magnetic fields and magnetic forces in vCalc

Here are some other vCalc equations expressing relationships between physical phenomena and forces due to magnetism:

• Magnetomotive Force
• Magnetic Flux Density
• Lorentz Force
