The Invisible World of Magnetic Fields

The Invisible World of Magnetic Fields

The Invisible World of Magnetic Fields The Invisible World of Magnetic Fields A bar magnet is a seemingly ordinary piece of metal from which invisible magnetic field lines originate. These magnetic field lines effect any magnetic material in the vicinity of the magnet. Magnets have a north pole where, by ...

The Force of Magnetism

The Force of Magnetism

The Force of Magnetism The Force of Magnetism You may ask, how does the force of, Magnetism work? The force of magnetis,m is directed from one pole to another. A pole can be described as the point where lines of magnetic force come together. Most simple magnets have two poles (that makes them ...

Magnetism

Magnetism Magnetism is one of the main forces of nature, like the force of gravity. Like gravity, which causes objects to be attracted to each other, magnetis,m causes magnetized objects to be attracted to each other. In most cases, planetary magnetic fields are made by currents of molten material which move around ...

The Magnetic Field

The Magnetic Field

The Magnetic Field The Magnetic Field The force of magnetism causes material to point along the direction the magnetic force points. As shown in the diagram to the left, the force of magnetism is illustrated by lines, which represent the force. In this diagram, the force points from the positive pole to the ...

Lightning Formation

Lightning Formation

Lightning Formation Lightning Formation The sky is filled with electric charge. In a calm sky, the positive (+) and negative (-) charges are evenly spaced throughout the atmosphere. Therefore, a calm sky has a neutral charge. Inside a thunderstorm, the electric charge is spread out differently. A thunderstorm is made up of ...
