What is Magnet?
[[File:Bar magnet.jpg|thumb|Bar magnet]] A '''magnet''' is a special kind of [[metal]] which is made out of (Iron Nickel and Cobalt) When a magnet goes near a special kind of metal or another [[magnet]], and the poles (sides) touching are opposite, it will pull, or ''attract'' the other object closer. If the two poles are the same, the magnet and the other object will push away, or ''repel'', from each other. This attraction and repulsion is called ''[[magnetism]]''.All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other like south and south and north and north. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a [[magnetic field]]. == Types of magnet == '''Soft magnets''' (meaning impermanent magnets) are '''often''' used in [[electromagnet]]s some of the magnets are (bar magnet,wand and ball magnet). These increase (often hundreds or thousands of times) the [[magnetic field]] of a wire that carries an [[electrical current]] and is [[Solenoid|wrapped around]] the magnet. The field also increases with the current. Magnetic Materials: Soft Magnets. Soft magnetic materials are those materials that are easily magnetised and demagnetised. '''Permanent magnets''' have [[ferromagnetism]]. They occur naturally in some rocks, particularly [[lodestone]], but are now commonly manufactured. A magnet's magnetism decreases when it is heated and increases when it is cooled. It has to be heated at around {{convert|1,000|C|F |abbr=out}}. Like poles (S-pole and S-pole/N-pole and N-pole) will repel each other while unlike poles (N-pole and S-pole) will attract each other. Magnets are only attracted to special metals. [[Iron]], [[cobalt]] and [[nickel]] are magnetic. Metals that have [[iron]] in them attract magnets well. [[Steel]] is one. Metals like [[brass]], [[copper]], [[zinc]] and [[aluminum|aluminium]], silver are not attracted
