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
To demagnetize a magnet, cause disorder to the unit magnets within the magnetic material. Strike the magnet first with a hammer, heat it strongly, and then subject it to AC current to eliminate magnetic ability completely.Full Answer >
You can strengthen magnets by placing them in water, stacking them on top of each other or recharging them. The method of making a magnet stronger depends on the type of magnet you have, explains HowStuffWorks.Full Answer >
Many magnets by CMS Magnetics are given four or more stars out of five on Amazon.com. CMS Magnetics offers a variety of sizes, strengths and shapes of magnets, including blocks, discs, cylinders, cubes and speciality magnets.Full Answer >
The north and south poles, often called the negative and positive sides, of a magnet are determined by using the directional properties of magnets. The north pole of the magnet is attracted to Earth's geographical north pole, and the south pole is attracted to Earth's geographical south pole.Full Answer >
