AT the Royal Society of Edinburgh on February 20, Sir J. Alfred Ewing read a paper on “Models of Ferromagnetic Induction,” giving a detailed account of his most recent work in magnetism.

Electromagnetic induction can create a voltage by movement of a conductor in a magnetic field. This voltage can make current flow, and the effect is used in electricity generation and microphones.

If not, no heat is transferred. Fortunately, stainless steel is magnetic, so if you have a set of stainless steel pans and are about to invest in an induction cooktop, you won’t have to replace ...

Did you know that you can request a loaner induction cooktop for a two-week trial period through PG&E? Joyce Mercado explores the switch from gas to induction cooking at home. The post The Wonders of ...

A – The coil is at 0°. The coil is moving parallel to the direction of the magnetic field, so no potential difference is induced. B – The coil is at 90°. The coil is moving at 90° to the ...
