Instructions

Play through this interactive game to learn about Electric and Magnetic Forces. Suitable for Grade 6, Grade 7, Grade 8.

Main Concepts

The magnetic force is a non-contact force.

Like electric charges will repel each other.

The greater the strength of the magnets, the greater the strength of the magnetic force between them.

Electric charges within a neutral object can be induced into moving from one location to another by bringing an external charged object near the neutral object.

The shorter the distance between magnets, the greater the magnetic force between them.

Protons have a positive charge and electrons have a negative charge.

Electrons will move freely and distribute evenly along the surface of a solid conducting material.

Current is the flow of charged particles through a conducting material resulting from electric force.

The greater the magnitude of the electric charge, the greater the strength of the electric force between charges.

Opposite magnetic poles will attract one another.

The motion of a magnet can cause electric current to flow through a conducting material.

The greater the size of an iron core in an electromagnet, the greater the strength of the magnetic force produced.

An electromagnet is produced by wrapping current-carrying wire around an iron core.

Every magnetized material has a north and south magnetic pole.

The greater the number of batteries connected to an electromagnet, the greater the strength of the magnetic force produced.

Like magnetic poles will repel one another.

The motion of electric charges (current) can produce a magnetic field.

Opposite electric charges will attract each other.

Magnetic force is the force of attraction and repulsion between two magnetized objects.

When positive and negative charges are separated in different locations within an object, the object is polarized.

Discussion Questions

Before the Game

What are some things you already know about magnets? What charge do electrons carry in an atom? What charge do protons carry in an atom? What makes some materials have magnetic properties?

After the Game

How did you create a magnet using electrons and protons? What is meant by the poles of a magnet? How do the magnetic fields work with attraction and repulsion of materials? What is an electric current? Why are wires coiled?
