The Generator Effect

• As you the magnet, the magnetic field through the coil changes

  • Ising the stingth of the magnetfeld (so there are more fald lines that can be out)
• Generators work when the coil or the field is moving
• Electricity is super snefal in our daily lives, which means the gate effect is really important too
