​Describe what you see in this picture.

Draw

Circle the magnet in the photo.

Open Ended

How do you know that the object picking up the metal beams is a magnet?

What do you think the magnet is made from?

Multiple Choice

What is electromagnetism?

• Earth's magnetic field

• the relationship between electricity and magnetism

Draw

Circle the differences you see in this photo.

Draw

In this figure, you see two systems designed to show how the direction of a current in a straight wire affects the magnetic field that forms. In the system on the left, the current flows upward. Draw your predicted magnetic field lines for the system on the right, in which the current flows downward.

increased

Draw

Draw a straight wire and how the magnetic field forms.

Draw

Draw the magnetic field lines around the two stacked loops of wire.

Multiple Choice

Is the strength of the magnetic field inside the loop greater or less than the strength when there was just one loop of wire?

• greater
• weaker
• equal

What do you know about magnets?

Draw

The diagram shows that field lines spread out as you move away from the magnet. Do the spreading lines show that the magnetic force gets stronger or gets weaker with increasing distance?
