Temporary And Permanent Magnets

Anything with a magnetic field is called a magnet and a magnetic field is a charged area surround the magnet. Each magnet has two pole, one North, and one South. North and North poles repel as do South and South poles. North and South poles, however, attract one another. Magnets draw in anything made of iron and metals like cobalt, steel, and nickel. There are two kinds of magnets. There are soft, temporary magnets, and hard, permanent magnets.

Temporary ones only act like magnets when they are being influenced by another magnetic field. Without a magnetic field, it is not a magnet. Paperclips and nails are good examples. They can be magnetized, but they are not magnets. Soft magnets are also used in telephones. Electromagnets are sort of temporary magnets because without an electric current, they are not magnets.

Permanent magnets have a consistent magnetic field. Like a refrigerator magnet. They are attached to your frig by virtue of their own uninterrupted field to hold steady to the metal of the refrigerator until someone removes the magnet. Neodymium magnets are commonly known as rare earth magnets and are especially tough permanent magnets. They cost more than their weaker cousins, but because they are so strong, are affordable because it takes less magnet to do the same things. Cars, hard drives, credit cards, speakers, jewelry, speakers, and many other items are made using magnets of the permanent kind.

Magnets are used in many, many everyday items that you likely use on a regular basis. Many of their uses may surprise you. Without both these kinds of magnets, many electronic devices you enjoy the luxury of using would not exist, or would be less advanced. They are also enjoyable to mess around with and invent your own purposes for them.
