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.Continue Reading
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
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 >
Testing different magnets to determine their strength or building a linear accelerator with magnets are some science projects using magnets that are appropriate for children. Experiments such as these are available on HomeTrainingTools.com and Education.com.Full Answer >
The three primary metal elements that are attracted to magnets are iron, nickel and cobalt. These are also the metals used to create most magnets, although some more powerful magnets use rare-earth elements, such as gadolinium or neodymium.Full Answer >
Magnets that can be made easily from material found at home are called homemade magnets. These are very small and weak magnets. They are primarily for having fun and teaching children about magnetism.Full Answer >
