Attraction And Repulsion Between Magnets
Key Notes :
Magnetic Poles:
- Magnets have two poles: the North Pole and the South Pole.
- The like poles of magnets repel each other, meaning two North poles or two South poles push away.
- The unlike poles of magnets attract each other, meaning a North pole attracts a South pole.
Attraction:
- When a North pole is brought close to a South pole, they attract each other.
- The force of attraction is strongest at the poles of the magnet.
- This attraction pulls the magnets together.
Repulsion:
- When two North poles or two South poles are brought close to each other, they repel each other.
- The force of repulsion pushes the magnets apart.
Magnetic Field:
- Magnets have a magnetic field that spreads out from the North pole and curves around to the South pole.
- The magnetic field is stronger near the poles and weaker away from them.
Demonstrating Attraction and Repulsion:
- A simple experiment can show attraction and repulsion. If you bring two magnets together, one with its North pole and the other with its South pole facing, they will attract. If both North poles are facing, they will repel.
Applications of Magnetic Attraction and Repulsion:
- Magnets are used in various applications such as in electric motors, compasses, and magnetic levitation trains (maglev).
- Magnetic attraction is used in holding objects like refrigerator magnets, while repulsion is used in devices that work with magnetic fields.
Important Concept – Magnetic Force:
- The force of attraction or repulsion depends on the distance between the poles and the strength of the magnet.
- The closer the poles are, the stronger the attraction or repulsion.
