Draw a diagram of a permanent magnet and state it's basic properties? Use bullet points to write your answer?

- A permanent magnet is a material that produces a magnetic field without the need for an external power source.
- It has two poles, a north pole and a south pole, which attract or repel each other depending on their orientation.
- The magnetic field produced by a permanent magnet is strongest at the poles and decreases in strength as you move away from them.
- Permanent magnets can be made from materials such as iron, nickel, and cobalt, as well as certain alloys and rare earth metals.
- They are commonly used in various applications such as electric motors, generators, speakers, and magnetic storage devices.

Basic Properties of a Permanent Magnet:

- Attractive to ferrous metals: Permanent magnets attract objects made of iron, nickel, and cobalt.
- Two poles: Each permanent magnet has two distinct poles called the North pole and the South pole.
- Magnetic field: Permanent magnets create an invisible magnetic field around them, which exerts a force on other magnets and magnetic materials.
- Magnetic field orientation: The magnetic field lines extend from the North pole to the South pole, forming a closed loop.
- Persistence of magnetism: Permanent magnets retain their magnetic properties indefinitely under normal conditions.
- Magnetic strength: The strength of a permanent magnet is measured in Teslas (T) or Gauss (G).
- Polarity: The North pole of a permanent magnet attracts the South pole of another magnet and repels its North pole.
- Demagnetization: Permanent magnets can be demagnetized by exposing them to extreme heat, strong magnetic fields, or physical shocks.
