1
Can we create electricity from a magnetic field? Electromagnetic Induction
2
Electric current can be created using a magnet by 2 different methods: 1. By moving a conductor inside of a magnetic field.
3
2. By moving a magnet around a conductor. Therefore, by using magnets you can control the current in your circuit.
4
Different Types of Switches
5
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.
6
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
7
Toggle switch, ex: light switch Push-button switch, ex: power button on most appliances
8
Magnetic contact switch, ex: alarm system, the magnet is pulled away from the switch when the door opens and the alarm goes off.

Could you figure it out?

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.
