A magnet always has -------- poles

279.9k+ views
Hint: A magnet is a material which produces a magnetic field around it. A magnet will attract and repel each other due to the magnetic field. When a magnet is suspended through a string it always points in the north-south direction. These are often referred to as the North Pole and South Pole and like poles repel each other and unlike poles attract each other.

Complete step-by-step solution:
A magnetic material exhibits a magnetic field around itself. This field can be visualized in front of lines originating from the north pole of the magnet and ending at the South Pole .These hypothetical lines are called magnetic field lines.

Properties of magnetic lines of force are:
$>$ Magnetic line density reduces as the distance between the poles increases
$>$ Magnetic field lines start from the North Pole and end at the South Pole.
$>$ Magnetic lines will not intersect with one another.
Two magnetic lines of force cannot intersect each other because if two magnetic field lines intersect there will be two directions of magnetic field at that point which is impossible.
A magnet always comes with a pair of magnetic poles and cannot be separated. . These are often referred to as the North Pole and South Pole.
So a magnet always has two poles.

Note: Magnetic lines of force which originate from a north pole and end at south pole and there cannot exist an isolated north pole or south pole. Magnetic monopoles do not exist in nature. Earth which produces its own magnetic field. Tesla is a unit of magnetic field strength (magnetic flux density).
