which made the needle behave like a magnet. You had to rub in one direction to get the atoms to all line up in the same manner. If you had rubbed back and forth, the atoms would not have lined up as well, and the magnetic field would probably not be as strong, if one was create...

To make a magnet repel a metal, one must first understand the properties of a magnet. A magnet has two poles, a north pole and a south pole. When magnets are placed near each other, opposite poles attract and like poles repel one another. When a metal enters a magnetic field, all of...
How to make a magnetic field stronger. How is the magnetic field oriented around a magnet? How do you increase the magnetic field of a magnet? How to create a static magnetic field. What is an induced magnetic field? How does the magnetic field act like a shield?
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...
How to Make an Electromagnet Leave about a 4” end of wire loose and then tightly wrap the wire around the nail or bolt. Wrap it as many times as possible leaving just a small amount of exposed metal at each end. The more coils, the stronger the electromagnet. Secure with tape. Leave...
To make a permanent magnet, all you have to do is encourage the magnetic domains in a piece of metal to point in the same direction. That's what happens when you rub a needle with a magnet — the exposure to the magnetic field encourages the domains to align. Other ways to align magn...
that act like tiny magnets. Normally, these domains do not exhibit any magnetism. However, when exposed to a magnetic field, the domains start to align and the individual magnetic fields unify into a bigger field. The degree of domain alignment depends on the strength of the magnetic field. ...
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...
