property of magnetsim
-
They are: Attractive Property – Magnet attracts ferromagnetic materials like iron, cobalt, and nickel. Repulsive Properties – Like magnetic poles repel each other and unlike magnetic poles attract each other. Directive Property – A freely suspended magnet always points in a north-south direction.
Unlike Pole
When a north pole and south pole point together, the arrows point in the SAME direction so the field lines can join up and the magnets pull together (attract).
Like Pole
A bar magnet suspended in Earth's magnetic field orients itself in a north–south direction. The north-seeking pole of such a magnet, or any similar pole, is called a north magnetic pole. ... Unlike poles of different magnets attract each other; like poles repel each other.
When do the magnet repl
When you place the north pole of one magnet near the south pole of another magnet, they are attracted to one another. When you place like poles of two magnets near each other (north to north or south to south), they will repel each other.
Magnetic material
A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc
History of magnet
The history of magnets begins with the first discoveries of magnetic stones or lodestones – starting from 1845 this kind of stone was called magnetite. It is a mostly black mineral of iron and oxygen or iron hydroxide, which develops in a natural way by volcanic activity and has its own magnetic property.
man made magnet
Examples of permanent artificial magnets include the magnets on your refrigerator door and neodymium magnets. The magnets for your refrigerator door can be made in any shape and for whatever purpose you need. These magnets are also used for magnetic bulletin boards and magnetic knife racks.
