Properties of magnets and their poles
- A magnet is an object that attracts magnetic materials, mainly iron, nickel and cobalt.
- Its magnetic effect is strongest at the north pole and the south pole, and it becomes weaker toward the middle of the magnet.
- Like poles repel north with north, and south with south.
- Unlike poles attract north with south.
- A single isolated pole cannot be obtained. If a magnet is cut into two pieces, each piece has a north pole and a south pole.
- A magnet produces a magnetic field around it, shown by lines that leave the north pole and enter the south pole.
- The closer the lines are, the stronger the field.
