1. Electromagnetic Force

2. 2 Components of the Electromagnetic Force
Electric Force – causes static electricity and causes the flow of electric charge to make electrical currents
Magnetic Force – associated with magnets
Both forces are caused by their fields – the field produces the force
Electromagnetic force describes the push and pull of objects based on charge and distance

3. Coulomb’s Law Charged particles exert forces on each other
Like charges repel unlike charges attract (just like poles of a magnet)
The greater the distance between the charges, the less force they exert on each other.

4. Magnetic Force
Opposite poles of magnets attract while like poles repel – north and south attract, north and north or south and south repel
The attraction or repulsion is the magnetic field

5. Electricity and Magnetism
Electricity and magnetism are components of the same force
They are dependent on one another and influence each other
Electricity creates a magnetic field and a magnetic field can be used to produce electricity

6. Electromagnets
And electromagnet is made by coiling a wire around a conducting core
When electricity runs through the wire and core a strong magnetic field is created
It can be turned on and off by turning the electric current on and off

7. Induction Generators
An electric current can be created by moving a magnet though a coil – this is called electromagnetic induction
Generators use electromagnetic induction to produce an electric current.
