Magnets and magnetic materials Magnets attract objects made of magnetic materials Magnetic materials include the elements iron, nickel, cobalt, alloys containing some of these such as steel and some of their compounds. iron nickel cobalt stainless steel Hard and soft magnetic materials Permanent magnets...
英文:Some objects are magnetic and can generate a magnetic field, exerting a force on other magnetic substances. This force can be either attractive or repulsive. For example, common refrigerator magnets use the magnetism of magnets to attach to the r...
Unlike poles of two magnets attract each other, whereas like poles repel each other. The materials that are attracted towards a magnet are called magnetic materials. The needle of a magnetic compass rests along the north-south direction. A magnet always has two poles....
Magnetism is what gives magnets theirability to attract objects made of iron or steel. A magnet creates around itself a region of space with special properties. This region is known as amagnetic field. When two magnets come near each other, their fields create forces thatattract or repel. ...

Strong magnets made of different materials have the potential to attract iron objects and hold them permanently in the selected position. This property makes the areas of application for magnetism in everyday life inexhaustible:Magnetic materials serve as fasteners onbagsand cupboard doors, as magnets...
If you hold two magnets in your hands, the north pole of one magnet will always attract the south pole of another. Opposite poles push each other away. Because our planet is like a big magnet, it also has a magnetic field. Earth's magnetic field protects us from the sun's radiation....

Magnets are objects that produce magnetic fields and attract metals like iron, nickel and cobalt. The magnetic field's lines of force exit the magnet from its north pole and enter its south pole. Permanent or hard magnets create their own magnetic field all the time. Temporary or soft ...
Magnetism astounds everybody when they first encounter it. Magnets attract some objects as if by magic, but only specific materials respond to a magnet. Understanding which materials respond and which don't is quite simple, but it depends on an understanding of how magnets work in general. Whil...
