An effective transformer design requires a determination of the peak values of the magnetic flux, the magnetic field strength, and the permeability of a core at low and high frequencies. These ...

Inductors are deceptively simple. However, a closer look reveals underlying complexity. How else can you explain the many types of core materials, types of windings, sizes, geometries and wide range ...

Deep beneath our feet, something extraordinary is happening. Scientists have discovered that changes in Earth's core are directly influencing our planet's magnetic field in ways we're only beginning ...

A University of California, Berkeley, geophysicist has made the first-ever measurement of the strength of the magnetic field inside Earth’s core, 1,800 miles underground. The magnetic field strength ...

In this article, I want to use an MRI (magnetic resonance imaging) medical scanner design as a familiar example for what needs to be done in a power supply design architecture to allow it to function ...
