Magnetic Fields - Force & Energy Flashcard

Front

What is a Magnetic Field?

Back

A region around a magnet where magnetic forces can be detected.

Front

What is Magnetic Force?

Back

The attraction or repulsion that arises between charged particles due to their motion.

Front

How can we increase the Magnetic Force in a system of Repelling Magnets?

Back

By using stronger magnets or moving the magnets closer together.

How can we increase the Magnetic Force in a system of Attracting Magnets?

Back

By using stronger magnets or moving the magnets closer together.

Front

What is Potential Energy?

Back

Energy that is stored and not currently being used.

Front

What is Kinetic Energy?

Back

Energy that an object possesses due to its motion.

Front

What happens to Potential Energy when an object is lifted?

Back

It increases as the object is moved against the force of gravity.

Front

What is the relationship between Potential Energy and Kinetic Energy?

Back

They can convert into each other; as potential energy decreases, kinetic energy increases and vice versa.

Front

What is the formula for calculating Potential Energy?

Back

Potential Energy (PE) = mass (m) × gravity (g) × height (h).

Front

What is the effect of distance on Magnetic Force?

Back

The magnetic force decreases as the distance between magnets increases.
