• Opposite poles pull toward each other

• Same poles push away from each other

• Larger magnets have stronger magnetic force

• Fields are stronger closer to the magnet and weaker farther away

Magnetic Field Facts

• Opposite poles pull toward each other
• Same poles push away from each other
• Larger magnets have stronger magnetic force
• Fields are stronger closer to the magnet and weaker farther away

The Power of Magnets

Magnets can attract and repel through various materials. Larger magnets have stronger attractions and can pick up metal in dirt or sand. When opposite poles are near, they attract. Bigger magnets have stronger repulsion.

Multiple Choice

What happens when opposite poles of magnets are near each other?

• They attract

• They repel

• They have no effect on each other

• They create a magnetic field

Magnetic Attraction

Trivia: When opposite poles of magnets are near each other, they attract. This phenomenon is due to the magnetic field lines of the magnets interacting with each other. It is this attraction that allows magnets to stick to metal objects and create a variety of useful applications in our daily lives.

The Power of Magnets

Magnets can repel through other materials, such as in washing machine barrels and magnetic trains. Similar poles repel each other, while opposite poles attract. The magnetic field can pass through materials and is strongest near the magnet.
