1
Now there is a circuit, and the bulb is on. Circuit-the path along which on electric current flows. (circle) Study this picture!
2
This circuit would have two lit bulbs. This circuit would have one lit.
3
Series circuit An electric circuit with only ONE path for the current (If one light goes out they all go out)
4
Parallel circuit An electric circuit with more than one path for the current (If one light goes out the others stay on)
5
Insulator – Any material that does not allow electric current to pass through it plastic rubber glass cloth wood like the protective coating on wires
6
Electromagnet is an electric circuit that creates a magnetic field. If the battery is disconnected the electromagnet CAN be turned off. A regular magnet can NOT be turned off. For an electromagnet to have a magnetic field it must be connected to a circuit. Electric currents produce magnetic fields. Electromagnets are used in motors. Can you draw this?
7
Electrical energy Electrical energy results from the movement of electrons. Electricity can be used to produce light. A toaster uses electrical energy to heat bread.
8
Compass In order to make a compass you must have a magnet The earth is one giant magnet A compass can detect the Earth’s magnetic field. Compasses all point the same way because of the Earth’s magnetic field. A compass is a magnet that can swing freely in any direction to detect a magnetic field.
9
Different charges attract Charges that are the same repel each other. Objects will attract or repel each other if they are charged. Clothes from a dryer will attract. Your hair will repel.
10
Magnets Magnets have 2 poles. North and South
11
What magnets repel? (repel=go away)
