Magnetic Force
Magnetic force is the force exerted between magnets and magnetic materials. It is a fundamental force of nature that is responsible for the attraction or repulsion between objects that have magnetic properties.
Magnetic Materials
- Materials that can be attracted by a magnet are called ferromagnetic materials. Examples include iron, nickel, and cobalt.
- Materials that are not attracted by a magnet are called non-magnetic materials. Examples include wood, plastic, and glass.
Magnetic Poles
Magnets have two poles: a north pole and a south pole. Like poles repel each other, and unlike poles attract each other.
Magnetic Field
A magnetic field is the area around a magnet where it exerts a magnetic force. The magnetic field is strongest at the poles of the magnet.
Magnetic Force and Motion
When a magnet and a magnetic material come close to each other, they can exert a force on each other. This force can cause the objects to move toward or away from each other, depending on their relative positions and poles.
Study Guide

LIFE SCIENCE
From Molecules to Organisms: Structures and Processes
Create representations to explain the unique and diverse life cycles of organisms other than humans (e.g., flowering plants, frogs, butterflies), including commonalities such as birth, growth, reproduction, and death.
Unity and Diversity
Construct an argument from evidence to explain the likelihood of an organism’s ability to survive when compared to the resources in a certain habitat (e.g., freshwater organisms survive well, less well, or not at all in saltwater; desert organisms survive well, less well, or not at all in woodlands).
Create models that illustrate how organisms and their habitats make up a system in which the parts depend on each other.
