MAGNETISM
It _ for centuries that certain black, heavy stones have the property of _ iron, this property is called magnetism. A magnet is a body that exhibits magnetism.
The two parts of a magnet that show the _ magnetism are called the North pole and the South pole.
Magnets not only affect ordinary iron, but they affect one another. When a pole of one magnet _ toward a pole of the _ magnet, they won't attract if both are north poles or both are south poles, but they will attract if one is a north pole and the other a south pole.
The region in which magnetic forces act is called a magnetic field. Iron _ in a strong magnetic field becomes magnetized.
Electricity and magnetism are _ connected. Many practical applications have resulted from the _ of the magnetic effects of an electric current. These effects are used in motors, in most electric meters, in electromagnets and in practically all electromechanical apparatus.
