Non-contact Forces: Magnetic Force

Front

What are non-contact forces?

Back

Forces that act on an object without physical contact, such as magnetic and gravitational forces.

Front

What is magnetic force?

Back

A non-contact force that can attract or repel objects due to their magnetic properties.

Front

Where are the north and south poles of a magnet located?

Back

The north pole is the end of the magnet that points toward the Earth's north when freely suspended, while the south pole points toward the Earth's south.

Front

What is the Earth's magnetic field?

Back

A magnetic field that surrounds the Earth, extending from the Earth's interior out into space, influencing compass needles and other magnets.

Front

How does a compass work?

Back

A compass works by aligning its needle, which is a small bar magnet, with the Earth's magnetic field, pointing towards the magnetic north.

Front

What is a magnetic field?

Back

The area around a magnet where magnetic forces can be detected and where other magnetic materials can be influenced.

Front

What happens when like poles of two magnets are brought close together?

Back

Like poles repel each other; for example, north-north or south-south will push away from each other.

Front

What happens when opposite poles of two magnets are brought close together?

Back

Opposite poles attract each other; for example, north-south will pull towards each other.

Front

What is the strength of a magnetic field?

Back

The strength of a magnetic field is strongest at the poles of a magnet and decreases with distance from the magnet.

Front

What is the area of influence surrounding a non-contact force called?

Back

Field.
