Magnetism (Introduction)

​Magnetism

Standards and Objectives​

​

 8.PS2.1

Design and conduct investigations depicting the relationship between magnetism and electricity in electromagnets, generators, and electrical motors, emphasizing the factors that increase or diminish the electric current and the magnetic field strength

​

Objective:​

• I can identify properties of magnetism.

• I can describe the structure and impact of Earth's magnetic field.

Multiple Choice

What type of force is a magnet?

• Contact

• Non-Contact

Multiple Choice

How many poles do magnets have?

• 1

• 3

• 2

• 4

A magnetic material is one which can be magnetized and is attracted to magnets.

​

A non-Magnetic materials can not be magnetized or attracted to magnets. Includes metals! ​

Fill in the Blank

Magnetic or Non-magnetic: Aluminum, Copper, Lead, Brass, Plastic are examples of ___________ materials....

Fill in the Blank

Magnetic or Non-Magnetic: Iron, Nickel, Cobalt, Steel are examples of _________ materials.

​Why do Magnets attract things?

The magnetic field is the area around a magnet that has a magnetic force.

​

There is a magnetic field line that show two things:

1. The lines show the direction of the field (will sometimes have an arrow)

2. Where the lines are the closest together is where the field is the strongest. ​

​Draw Activity!

Use a whiteboard and your peers to draw pictures of the following! Use the information I just gave you to help you with the drawing!

​

A. Draw a picture of two magnets that are repelling each other.

B. Draw a picture of magnets that re attracting to each other. ​

Remember this​!

The Magnetic field always comes out of the north pole to the south pole.​
