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 ...
A company site describing a technique for producing small quantities of conducting material. This is a good applied physics site especially when discussing electromagnetic induction
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.
Hans Reichenbach (1891 - 1953) wrote on quantum mechanics, time, induction, probability and the philosophy of science.
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 ...
Very brief biography Michael Faraday (1791-1867), the discoverer of electromagnetic induction.
An article about the huge magnetic field that surrounds the Earth and stretches into space.
An article looking at some of the techniques used in archaeological geophysics that helped in the recent Stonehenge discovery, including earth resistance, magnetometry, ground-penetrating radar and ...
