A quick explanation of the process that causes the Earth's magnetic field.
This page explains hysteresis in magnetic materials, and how it can be used for magnetic recording.
A simple demonstration enabling us to visualize magnetic fields in 3D.
Play golf with a twist using protons in magnetic fields. Start with simple fields, then move all the way up to golfing in Earth’s magnetic field.
Every 11 years the direction of the Sun's magnetic field flips. This article outlines what we expect to observe and experience here on Earth when it does change direction.
When an emf is generated by a change in magnetic flux according to Faraday's Law, the polarity of the induced emf is such that it produces a current whose magnetic field opposes the change which ...
Electric motors involve rotating coils of wire which are driven by the magnetic force exerted by a magnetic field on an electric current. They transform electrical energy into mechanical energy.
An exploration of the earth's magnetic field and the links between magnetic anomalies and the geology of the San Francisco Bay area.
Electromagnets are usually in the form of iron core solenoids. The ferromagnetic property of the iron core causes the internal magnetic domains of the iron to line up with the smaller driving ...
An article about the huge magnetic field that surrounds the Earth and stretches into space.
