- Topic 7 -Magnets
- Electromagnet
- When a current flows through a wire, a magnetic field is made.
- Changing the direction of the current changes the magnetic field.
- The strength of the magnetic field changes depending on the size of the current and the amount of wire.
- Induced magnets
- Whenever an object that isn't a magnet becomes attracted to a magnet, it becomes an induced magnets.
- This happens when it enters the magnetic force of an object.
- Induced magnets are also known as mono-poles... meaning that they only have a north or south pole (which they have depends on which magnetic pole's force it entered)
- Induced magnets are only temporarily magnets. Once they leave the magnetic field, they become normal objects again.
- Whenever an object that isn't a magnet becomes attracted to a magnet, it becomes an induced magnets.
