I WONDER - What Is Magnetism?

Magnetism is a force that acts at a distance, similar to gravity, but it occurs between magnets or between magnets and materials like iron or steel. Magnets have two poles, North and South, with opposite poles attracting and like poles repelling. The Earth functions as a giant magnet with a magnetic field extending into space, crucial for navigation and protection from solar radiation.

What is a key characteristic of magnetism?

• It acts at a distance.

• It is weaker than gravity.

• It acts only on living organisms.

• It requires direct contact.

Which materials are typically affected by magnetism?

• Plastic and wood

• Iron and steel

• Copper and aluminum

• Glass and rubber

What happens when two North poles of magnets are brought close to each other?

• They have no effect on each other.

• They become stronger.

• They repel each other.

• They attract each other.

How does the Earth function in terms of magnetism?

• As a small magnet with a limited field

• As a giant magnet with an extensive field

• As a magnet with no poles

• As a magnet that only affects the moon

What is one of the roles of Earth's magnetic field?

• To attract more meteors

• To make the Earth spin faster

• To protect us from harmful solar radiation

• To increase the Earth's temperature
