Forces of Electricity and Magnetism

Electricity and Magnetism

by Adonna Joseph

​MS-PS2-3:

Ask questions about data to determine the

factors that affect the strength of electric

and magnetic forces.

​

​What does this mean?

​Electric and magnetic (electromagnetic) forces can be attractive or repulsive, and their sizes depend on the magnitudes of the charges, currents, or magnetic strengths involved and on the distances between the interacting objects.
