Electromagnetic Induction
• Can we create electricity from
a magnetic field?
Electromagnetic Induction
• Electric current can be created using a magnet
by 2 different methods:
• 1. By moving a conductor inside of a magnetic
field.
• 2. By moving a magnet around a conductor.
Therefore, by using magnets you can control the current in
your circuit.
Different Types of Switches
Electrical Function
• The function that an electrical switch fulfills is
called control.
• The purpose of a control is to open and close
an electric circuit.
Forms of switches.
• All of these are binary, meaning they are
either completely on (contact made) or
completely off (contact broken).
• Rocker switch, ex: power bar switch
• Toggle switch, ex: light switch
• Push-button switch, ex: power button on most
appliances
• Magnetic contact switch, ex: alarm system,
the magnet is pulled away from the switch
when the door opens and the alarm goes off.

Types of Switches
Your task
• Circuit design:
– Create a circuit that contains the following
elements:
• 4 light bulbs each controlled separately.
• A resistor
• Only 2 switches.
• You may work with a partner.
• Draw your circuit on a loose leaf and hand it in.
