 Basic Electronics -- Online book which covers topics from ohms law to digital circuits. Contains interactive troubleshooting simulations.
Basic theory of -- Electricity and Magnetism
CdTe Gamma Detectors Equipped With Ohmic Contacts -- Gamma induced currents in CdTe and CdZnTe semiconductor detectors equipped with ohmic contacts are not sensitive to hole trapping.
Differential Forms in Electromagnetic Theory -- The differential forms research group at BYU is investigating the use of the calculus of differential forms in teaching and research. Differential forms have been used to express Maxwell''s laws since early in this century, but many of the advantages of forms as a tool for applied electromagnetics have only recently been discovered.
Electrodynamics in Relativistic Notation -- Familiarize yourself with Lorentz scalars, covariant and contravariant vectors and tensors, lorentz scalars, and how to use relativistic notation to describe charge conservation, the d''Alembertian, the inhomogenous wave equation for potentials, and the electromagnetic Lorentz scalars.
Electromagnetic Fields and Forces -- The forces on charged particles due to electromagnetic fields are introduced and related to the general case of force on a particle by a gauge field. Also covers the electromagnetic four-potential. Section of book A Radically Modern Approach to Introductory Physics by D. Raymond.
Electromagnetic Induction -- A virtual experiment on creating electric current with a changing magnetic field.
Electromagnetic Spectrum -- A NASA site listing the various wavelengths of electromagnetic radiation.
Electromigration -- Surface electromigration refers to the directed motion of atoms (adatoms) at solid surfaces, grain boundaries and interfaces which is caused by an electric current in the bulk of the material. It is considered a key factor determining the reliability of integrated circuits.
How Solar Cells Work -- Principles of operation of silicon photovoltaic cells.
How Van de Graaff Generators Work -- Description of Van de Graaff generators and static electricity, from How Stuff Works.
How a Compass Works -- Explanation of how compasses work and how to make your own, from How Stuff Works.

We also provide free software downloads featuring interactive analog and digital troubleshooting.
Static Electricity Page -- Appears to be a page devoted to projects which can be built by the amateur scientist related to static electricity.
The ElectroScience Laboratory -- indoor anechoic chamber RF measurement facility at the Ohio State University , college of engineering.
The Electromagnetic Field Tensor -- A page of notes on advanced methods of electromagnetism
The Van de Graaff Generator Website -- This site includes information on how Van de Graaff Generators work and instructions for building one. There are pictures of one built using these steps.
VRML Gallery of Electromagnetism -- a visualization of the electromagnetic field
Vacuum Tube Diode -- A demonstration of how a vacuum tube diode works.
X-ray Optics and Microscopy at Stony Brook -- Use coherent soft x rays for optics experiments. Most research effort is directed towards using Fresnel zone plates to produce the smallest focused spot of electromagnetic waves of any wavelength, and exploiting that microfocused beam for studies of biological and materials science specimens.
