Magnetic fields

• A magnet is an object capable of exerting a magnetic force.
• Magnets have two poles: a north pole and a south pole.
• In a magnet, the end that is attracted to the Earth's magnetic north pole is referred to as the north pole.
• In a magnet, the end that is attracted to the Earth's magnetic south pole is referred to as the south pole.
• Magnetic force is strongest near the magnet's poles.
• Two magnets will either attract or repel each other in the following way: like poles (N-N or S-S) repel, while unlike poles (N-S or S-N) attract.
• Magnetic forces are non-contact forces.
• A force exerted between two objects, even when they are not touching, such as the force of gravity, is known as a non-contact force.
• Magnets affect each other without touching due to the force of magnetism.
• Induced and permanent magnetism are two types of magnetism.
• Electromagnets and transformers are examples of devices that use magnetism.
