  • Magnetism is a force that causes attraction or repulsion between objects. Magnetism is a force that causes attraction or repulsion between objects. Magnets always contain metal. Magnets always contain metal. The atoms in a magnetic material, like iron or steel, all point in the same direction. The atoms in a magnetic material, like iron or steel, all point in the same direction. Magnetic force can travel through many materials, even water. Magnetic force can travel through many materials, even water.

  • Magnets attract only certain types of materials which are: steel, iron, cobalt, and nickel. Magnets attract only certain types of materials which are: steel, iron, cobalt, and nickel. Every magnet has two poles. Every magnet has two poles. The poles are the points where the magnetic force is strongest. The poles are the points where the magnetic force is strongest. One pole is called the north pole. One pole is called the north pole. The other is the south pole. The other is the south pole.
