Amplify Magnetic Fields Review

What is a magnetic field?

Back

A magnetic field is an invisible field around a magnet where magnetic forces can be felt. It is created by moving electric charges or magnetic materials.

Front

What happens when two magnets are brought close together?

Back

They can either attract or repel each other depending on their poles. Opposite poles attract, while like poles repel.

Front

What is the difference between attraction and repulsion in magnets?

Back

Attraction occurs when opposite poles of magnets come together, while repulsion occurs when like poles push away from each other.

Front

What is the role of force in motion?

Back

Force is needed to change the motion of an object. It can start, stop, or change the direction of an object's movement.

Front

What is the effect of distance on magnetic force?

Back

The strength of the magnetic force decreases as the distance between two magnets increases.

Front

What is a magnetic pole?

Back

A magnetic pole is one of the two ends of a magnet where the magnetic force is strongest. Every magnet has a north and a south pole.

Front

How do magnetic forces work at a distance?

Back

Magnetic forces can act at a distance without direct contact, allowing magnets to attract or repel each other even when separated.

Front

What is the principle of magnetic attraction?

Back

Magnetic attraction occurs when the north pole of one magnet is near the south pole of another, causing them to pull towards each other.

Front

What happens to magnets when they are not touching?

Back

Magnets can still exert a force on each other even when not touching, causing them to move closer or repel each other.

Front

What is the significance of the direction of force?

Back

The direction of force determines how an object will move. Force can act in the same direction as motion, opposite, or at an angle.
