One method is to make a magnet out ofa mixture of different types of metal. The metal is heated and melted, then placed in a cast, or container that's used to make a shape. The metal cools in the cast. Then magnetism is added to it, usually with a powerful electromagnet that's bee...
Magnets are usually made of metal iron, or another material that has lots of iron in it, such as steel. Magnets can be of various shapes, but all of them have the ability to pull things towards themselves. This invisible force is called magnetism. Magnets only attract (pull) metals that ...
When a magnetic compass is placed at different points on a magnetic line of force, it aligns itself along the tangent to the line of force at that point. These are just some of the basic concepts of magnetism. One cannot possibly grasp the depth and appreciate the versatility of magnets wi...
Originating from Earth’s core and atoms themselves, magnetism is the invisible force that shapes our everyday lives. Here’s how magnets actually work.
What we can find out this way, is some of the basics of magnetism, like:the north pole of the magnet points to the geomagnetic north pole (a south magnetic pole) located in Canada above the Arctic Circle. north poles repel north poles south poles repel south poles north poles attract ...
This on-demand magnetism is what makes the electromagnet so useful. Key Figures in the History of Electromagnets The field of electromagnetism attracted many brilliant minds over the course of several decades. Here are four individuals who made some of the most important discoveries. James Maxwell...
In the world of magnetism, a distinction is made between two types of magnets: permanent magnets and electromagnets. Electromagnets depend on an electric current and can therefore be turned on and off. On the other hand, permanent variants are magnetic in and of themselves and cannot be switched...

Magnetic and electrical fields are related, and magnetism, along with gravity and strong and weak atomic forces, is one of the four fundamental forces in the universe. But none of those facts answers the most basic question: What exactly makes a magnet stick to certain metals? Or why don't...
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 created at all. Magnetism created in this manner is called induced magnetism...
