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.
Felix Bloch (1905 - 1983) research lead to a new method of nuclear induction for the study of nuclear moments in solids, liquids, or gases.
If an electric current flows through a conductor in a magnetic field, the magnetic field exerts a transverse force on the moving charge carriers which tends to push them to one side of the conductor. ...
William Gilbert (1544-1603) work in 1600 was the standard work throughout Europe on electrical and magnetic phenomena. He made the first clear distinction between magnetic and the amber effect ...
The site allows the path of a charged particle to be tracked through a magnetic field perpendicular to the screen.
Wilhelm Eduard Weber (1804 - 1891) worked closely with Carl Friedrich Gauss and developed sensitive magnetometers and other magnetic instruments. The magnetic unit, termed a weber, formerly the ...
