electricity

• in a LDR, as light intensity decrease, resistance increase, meaning less current and dimmer bulb
• • Very few metals in the Periodic Table are magnetic. These include:
  • Iron
  • Cobalt
  • Nickel
• • In the motor effect, there is already a current in the conductor which experiences a force
  • In the generator effect, there is no initial current in the conductor but one is induced (created) when it moves through a magnetic field
