Electromagnetic Induction

magnetic fieldlines always travel north to south
The closer the magnetic field lines, the stronger the field
Amount of current can be changed by ...
1. strength of magnet
2. speed of the movement of magnet in and out
If magnet is moved in and out of coil wire, electricity is produced
1. electric current is induced because magnetic field around coil is changing
  1. The coil cuts through the lines of field
increasing the induced voltage
1. move the magnet faster
2. use a stronger magnet
3. increase the number of turns on the coil
4. increase the area of the coil
