star, and galaxy. The magnetic field surrounding Earth helps to protect us from the sun's violent rays and helps to create the auroras that light up the polar regions. Now you will be able to harness that power in your own little corner of the universe by creating your ...

Magnetic fields with downward curvature are not favourable for prominence formation since the presence of a small quantity of dense material at the summit of a low-beta arcade cannot deform sufficiently the magnetic field lines to remain there in a stable manner. Thus a dip at the field line ...
a nearby compass would change direction. This observation led to the conclusion that the electrons moving through the wire were creating a magnetic field that didn't exist when the current was turned off. An important thing to note is that charged particles create magnetic fields only when they...
I have a sphere of Terfenol-D in air as you know Terfenol-D is a magnetostrictive material, so when you apply a magnetic field its changes its shape. I want to model this thing in COMSOL that i want to apply a certain magnetic field and see how the shape of...
Whenever electricity flows through a wire, it creates a magnetic field. In a single wire, this field is usually pretty weak. A coil, however concentrates the magnetic field. Each coil of wire contributes a small magnetic field and, together, they add up to make a much more powerful magnet...

You can also go all out and create an electromagnet out of your metal that will create a magnet field that will either be attracted by or repelled by other magnets. To make an electromagnet out of your metal, wrap and coil wire around it completely and attach both ends of the wire to...
In magnets, on the other hand, most or all the magnetic domains point in the same direction. Rather than canceling one another out, the microscopic magnetic fields combine to create one large magnetic field. The more domains point in the same direction, the stronger the overall field. Each ...
