A magnetic field consists of imaginary lines of flux coming from moving or spinning electrically charged particles. Examples include the spin of a proton and the motion of electrons through a wire in an electric circuit.
Magnets are one of the rare items found in nature that are able to exert control over other objects without actually touching them. If you hold a magnet close to a certain type of object, it will either attract or repel it. This is due to the principles of magnetism.
Magnets have two ends (or poles). If you put the poles of two magnets together, they will either pull together or push apart. Magnets will pull (attract) each other if the poles are different. This invisible pull is called a magnetic force. Magnets will push (repel) each other if the poles are the same. This magnetic forces pulls against you.
Questions 1.What do you observe when you place two magnets next to each other North to North? South to South? North to South? 2.Why do magnets push or pull other magnets? 3.How did you determine if the paperclip would be a North or South pole?
