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.Know More
To strengthen an iron bar magnet, fill a bowl or pan with water. Find a small item to float in the water and place the magnet on top of the item. The magnet starts to twirl in the water until it rests and points directly north/south. Remove the magnet from the water and keep it in the same position while placing it on a hard surface. Then, strike one end of the magnet with a hard object repeatedly. The force can loosen small magnetic domains in the bar.
You can recharge a magnet that has lost its strength by repeatedly rubbing it against a very strong magnet. The strong magnet's pull realigns the magnetic domains in the weaker magnet.
The last option to strengthen magnets is to stack all the weak magnets together. This can be difficult, as magnets attract in opposite directions. For this method to be effective, you must clamp or hold the magnets together so they all face the same direction.Learn more about Magnetism
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 >
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 >
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.Full Answer >
Permanent magnets with diminished field strength can be recharged in at least three ways: by striking, stroking or stacking. Each of these methods entails lining up the weakened magnet with a stronger external field and using it to realign its particles.Full Answer >
