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 ...
- strength of magnet
- speed of the movement of magnet in and out
- strength of magnet
- If magnet is moved in and out of
coil wire, electricity is produced
- electric current is induced because
magnetic field around coil is changing
- The coil cuts through the lines of field
- The coil cuts through the lines of field
- electric current is induced because
magnetic field around coil is changing
- increasing the induced voltage
- move the magnet faster
- use a stronger magnet
- increase the number of turns on the coil
- increase the area of the coil
- move the magnet faster
