Skills Assessed 

​

Skill 809.1: 

Draw a diagram that illustrates the magnetic field that surrounds a bar magnet.  Label the poles, field lines, direction of field lines. Explain why a bar magnet is sometimes called a permanent magnet.

Draw a diagram that illustrates the magnetic field that surrounds Earth.  Label the poles, field lines, direction of field lines.  Explain how Earth’s magnetic field compares to a bar magnet in strength and size.

​

Skill 809.2: 

Draw and label a sketch of an electromagnet.  Build a simple electromagnet.  Explain how to make the electromagnet's field stronger or reverse the poles.  Explain how an electromagnet is a type of temporary magnet.

​

Skill 809.3: 

Draw and label a sketch of an electric generator.  Describe how an electric current is induced when a coil of wire is in a changing magnetic field (mechanical energy being changed to electrical energy.)  Build an electric motor.  Describe how  motion is produced when a coil of wire with an electric current in a magnetic field turns(electrical energy being changed to mechanical energy.)
