Magnetic
When we talk about something being "magnetic," we're referring to its ability to attract certain materials. This property is due to the presence of a magnetic field, which is a region around a magnetic material or a moving electric charge within which the force of magnetism acts.
Study Guide
- What is a magnetic field?
A magnetic field is a region around a magnetic material or a moving electric charge within which the force of magnetism acts. - How do materials become magnetic?
Materials become magnetic when the magnetic domains within the material align in the same direction, creating a net magnetic field. - What are the properties of magnets?
- They have two poles: north and south
- Like poles repel, and unlike poles attract - What are some examples of magnetic materials?
- Iron
- Nickel
- Cobalt - How are magnets used in everyday life?
Magnets are used in: - Refrigerator doors - Magnetic compasses - Magnetic toys and games - MRI machines in hospitals
Understanding the concept of magnetism and its applications can help us appreciate the role of magnets in various aspects of our lives and the natural world.

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.
