The Optical Microscopy Division of the National High Magnetic Field Laboratory (NHMFL) provides these state of the art Electricity & Magnetism Tutorials (For more from NHMFL, see the August 4, 1999 Scout Report for Science & Engineering
). The wide variety of interactive tutorials (Java) includes topics like Atomic Orbitals, Cathode Rays, Faraday's Electromagnetic Induction Experiment, Lenz's Law, AC and DC Generator Action, and more. The Atomic Orbitals tutorial, for example, lets users select any combination of the first four atomic orbitals (s, p, d, and f) and view their orientations in relation to x, y, and z axes. These tutorials provide simple and useful tools for visualizing concepts.
