All magnets have both a north and a south pole, which causes them to either repel or attract one another depending on how the two poles are lined up. If the north pole of one magnet meets the south pole of another, the two will be attracted, but if either both north or south poles meet, the magnets will repel one another.Continue Reading
No matter what type of magnet, the opposite poles always attract while similar poles always repel. Each magnet sends out a magnetic field, which is positive on one pole and negative on the other. This magnetic field is the result of the movement of negatively charged electrons within the magnet. These fields are strongest directly at the pole, which is why the ends of magnets will so powerfully repel or attract each other.
Magnets are constructed from one of the magnetic metals, such as iron, nickel or cobalt. These materials will always be attracted to a magnet, or they can be magnetized to form a magnet themselves. Steel is another magnetic material, as it is usually constructed mostly of magnetic iron.
To test whether a material is magnetic, it is necessary to use another magnet to see whether or not the two will repel one another.Learn more about Magnetism
Magnets have a north and south pole, and bringing two like poles together repels magnets while unlike poles attract each other. The distance in which two magnets begin to repel or attract each other is determined by the strength of the magnetic field.Full Answer >
According to HowStuffWorks, the bullet train, also referred to as the maglev train, works with the use of powerful magnets, metal coils and a large electrical power source. Maglev is a term that stands for magnetic levitation, which refers to how bullet trains quickly glide across railways.Full Answer >
The uses of magnets in everyday life include in the household, credit cards, electronics, industrial work, medical equipment and jewelry. In different industrial fields, magnets are useful as magnetic sweepers or sorters. Everyday electronics used in the home, such as televisions, computer disks and videotapes, also require magnetism to produce some type of magnetic field.Full Answer >
Car magnets usually stay in place while the vehicle is in motion as long as they are applied properly. Magnets stay on best when placed on areas of the car that are flat or slightly curved. Car owners should only apply them to metallic areas with minimal non-metal fillers.Full Answer >
