Faraday’s Law of Induction describes how an electric current produces a magnetic field and, conversely, how a changing magnetic field generates an electric current in a conductor.

Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it ...

As we approach solar maximum, something strange is happening to the sun's magnetic field. We explore this flip in polarity in more detail and look at the effects it could have on Earth.

The magnetic field is strongest at the center of the loop and weaker farther away, following an inverse square law. Outside the loop, the magnetic field resembles that of a dipole, with field ...

One of these laws — Faraday’s law of induction — clearly establishes that a magnetic field varying in time produces an electromotive force (EMF) on electrons flowing in a circuit.

There is another way to create a curly magnetic field—with a changing electric field. Yes, it's the same way a changing magnetic field creates a curly electric field. Here's what it would look like.

Magnetic field levels in all of the adjacent tenant areas and the second floor law offices ranged from 0.1 mG to 3 mG — a level below the pre-upgrade values. This suggested that the benefit of new ...

This is called Hale's law. "The magnetic field from active regions makes its way toward the poles and eventually causes the reversal," solar physicist Todd Hoeksema, director of the Wilcox Solar ...
