Magnets

• Magnets have a magnetic field around them
• Magnets have 2 opposite poles (North and South) which exert forces on other magnets. Like poles repel and unlike poles attract. This is caused by the interaction of magnetic fields.
• Magnets attract magnetic materials by inducing (permanent or temporary) magnetism in them.
• Magnets will exert little or no force on a non-magnetic material
• For magnets, the direction of an electric field at a point is the direction of the force on a positive charge at that point
