Developing your previous knowledge of magnetism we go onto study electromagnets and how their effects are used in real devices.

Choose your topic:

• Permanent Magnets [FREE] - There is always a magnetic field around these materials 

​

• Electromagnets - Here a current in a wire causes a magnetic field around it

​

• The Motor Effect - When there is a current in a wire inside a magnetic field it causes movement​

​

•  Motors  - These use the motor effect to cause rotation in everyday devices
