What are magnetic fields made of? A tremendous amount of research has gone into the area of elementary particle physics - the study of the basic building blocks of all the matter we know of. We used to think that electrons, protons, neutrons and photons were all there was. However, we ...
"Our data clearly show that electrons suddenly cease to follow magnetic fields and zoom off in another direction, corkscrewing and turning. That begs for explanation," Egedal said. The activity confirmed the theoretical descriptions of magnetic reconnection. But it has violated the standard law gover...
it causes the rising and falling magnetic fields to push the core of the motor around. Motors are ubiquitous–at least a dozen are in your car, there is one in every appliance, there is one in your computer to turn the hard drive, and there is ...
Magnetic Fields Magnetic fields can be created a few different ways, however the largest magnetic field we see is the that created by the rotating liquid outer core of the Earth. This has caused the formation of natural permanent magnets in the rocks on the Earth's surface. ...
Every school kid knows that Earth has a magnetic field – it's what makes compasses align north-south and lets us navigate the oceans. It also protects the atmosphere, and thus life, from the sun's powerful wind. But what about other Earth-like planets in the galaxy? Do they also have...

(Or have a magnetic field frozen in, something I don't understand.) I'd like to see the math, but I'm busy right now. I'm sure it is out there somewhere. Another wrinkle is that heavenly bodies with magnetic fields always have toroidal and poloidal fields. The Earth's toroidal ...
Magnetic field of Earth.(Image credit: alxpin via Getty Images) Magnetic fields are generated by the motion of electric charges, according to HyperPhysics. Electrons all have a fundamental quantum mechanical property of angular momentum, known as "spin." Insideatoms, most electrons tend to form...
How Magnetic Fields Are Created from Chapter 7/ Lesson 3 84K Magnetic fields are generated when charged particles move around. Explore more about magnetic fields, their source, current carrying conductors, and electromagnets and how they act. ...
Metals can be magnetic and non-magnetic. The magnetic ones will produce a field around them, usually described as “ferromagnetic.” These metals are not magnetic by themselves in their natural state. Still, they can be attracted to objects that produce magnetic fields. ...
