Magnetic Fields Chapter 3 Test

Front

What is a magnetic field?

Back

A magnetic field is a region around a magnet where magnetic forces can be detected. It is represented by magnetic field lines that show the direction and strength of the magnetic force.

Front

How does distance affect magnetic force?

Back

The magnetic force is stronger when you are closer to the magnet and weaker as you move further away.

Front

What unit is used to measure magnetic force?

Back

The unit used to measure magnetic force is the millitesla (mT).

Front

What is the relationship between energy and joules?

Back

Joules are the unit of measurement for energy. One joule is defined as the amount of energy transferred when a force of one newton is applied over a distance of one meter.

Front

What happens to a spacecraft magnet when it is released from a launcher magnet?

Back

When the spacecraft magnet is released, it moves away from the launcher magnet due to the repulsive magnetic force.

Front

What does Claim 3.B state about magnetic force?

Back

Claim 3.B states that the magnetic force was much stronger on Wednesday because the magnetic force is stronger closer to the magnets.

Front

What is the significance of the Sensor mT in the simulation?

Back

The Sensor mT measures the magnetic force in milliteslas during the simulation.

Front

What is the effect of stronger magnets on magnetic force?

Back

Stronger magnets produce a stronger magnetic force, which can affect the movement of objects within their magnetic field.

Front

How can you visualize a magnetic field?

Back

A magnetic field can be visualized using iron filings or magnetic field lines, which show the direction and strength of the field.

Front

What is the difference between energy and magnetic force?

Back

Energy is the capacity to do work, measured in joules, while magnetic force is the force exerted by a magnet, measured in milliteslas.
