There are 3 types of poles in science. A rotating sphere such as the planet Earth has two poles, which are where the rotation produces the minimum of motion, or which are where an imaginary axis of rotation emerges from the sphere. If an object is magnetic is has a magnetic north and south pole where lines of force can be imagined to emerge. And some objects such as water molecules have electrical poles, which are regions where there is either a positive or a negative charge.
A pole. They are called the north pole and south pole. The north pole of a magnet is defined as the pole that, when the magnet is freely suspended, points towards the Earth's North Magnetic Pole in the Arctic.
The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center
NORTH AND SOUTH
A horseshoe magnet has a North pole one one of the feet and a south pole on the other. A magnet made of flexible material would collapse on itself as the two poles attract.
a magnet attracts metal or steel ( this is from nick prager). And also iron.
