Physics of Magnetism

An Overview of the Exciting World of the Modern Physics of Magnetism and Magnetic Fields

The Physics of Magnetism and Magnetic Fields

Today, magnets and magnetism literally help the world go 'round and these fundamental forces have provided the source for countless innovations that have improved the standard of living for many people. As can be seen in the graphic on the cover, magnetic field lines are a way to visualize the magnetic field a magnet produces. Magnets produce vector fields at all points in the space around it.

This field can be defined by measuring the force the field exerts on a moving charged particle, such as an electron.

The physics of magnetism require an understanding of the concept of an electric field,. There is a fundamental relation between the force on a charge q in an electric field: = q. A magnetic field is the...
