Explore Explore Magnets and electromagnets have the following unique properties: Polarity Magnets and electromagnets have areas on their ends (if bar or horseshoe magnets) or on their tops and bottoms (if ceramic, plastic, or donut magnets) that are called poles. The magnetic pull or attraction is strongest at these poles. Every magnet has a North Pole and a South Pole.
Explore Explore Like poles repel each other. If the North Pole of one magnet and the North Pole of another magnet are brought close to each other, they will move away from each other; they will repel. The same thing happens if the South Pole of one magnet and the South Pole of another magnet are brought close to each other. Unlike poles attract each other. If the North Pole of one magnet and the South Pole of another magnet are brought close to each other, they will move toward each other; they will attract.
Explore Explore Attraction Magnets and electromagnets attract each other when unlike poles are near each other. Magnets attract certain types of metals, such as iron, nickel and steel. When iron nails or steel paper clips are held near a magnet, they will move toward, or be attracted to, the magnet. Repulsion Magnets and electromagnets can push each other apart if their like poles (North-North or South-South) are brought near each other.
Explore Explore Strength The strength of a magnet or electromagnet is how strong of an attracting repelling force the magnet exerts on objects around it. The attractive strength of a magnet or electromagnet is greatest at its poles. Some magnets have a greater strength than other magnets. The strength of a magnet or electromagnet can be measured and compared by counting the number of objects, for example paper clips the magnet can pick up.
