Amplify Magnetic Fields Pre-Assessment

Front

What happens to the potential energy when a magnetic object moves against the magnetic force?

Back

The potential energy increases because the object moves against the magnetic force.

Front

What happens to two magnetic objects placed very close to each other?

Back

They will move away from each other because the magnetic force will push them apart.

Front

What is the relationship between speed and kinetic energy?

Back

The kinetic energy increases as speed increases.

Front

What occurs when two magnets of the same polarity are brought close together?

Back

The magnets will repel each other.

Front

What occurs when two magnets of opposite polarity are brought close together?

Back

The magnets will attract each other.

Front

Define magnetic force.

Back

Magnetic force is the attraction or repulsion that arises between electrically charged particles due to their motion.

Front

What is potential energy in the context of magnets?

Back

Potential energy is the stored energy in a system due to the position of the magnets relative to each other.

Front

How do magnetic field lines indicate the strength of a magnetic field?

Back

The density of the magnetic field lines indicates the strength; closer lines mean a stronger magnetic field.

Front

What is the effect of distance on magnetic force?

Back

As the distance between two magnets increases, the magnetic force decreases.

Front

What is the principle of conservation of energy in a magnetic system?

Back

Energy cannot be created or destroyed, only transformed from one form to another.
