Magnetic Fields

Front

What is a magnetic field?

Back

A magnetic field is a region around a magnetic material or a moving electric charge within which the force of magnetism acts.

Front

What are the two types of magnetic poles?

Back

North pole and South pole.

Front

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

Back

They repel each other.

Front

Back

They attract each other.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.

Front

How can energy be transferred from potential to kinetic?

Back

Energy can be transferred from potential to kinetic when an object moves from a higher position to a lower position, converting stored energy into motion.

Front

What is the relationship between electricity and magnetism?

Back

Electricity can create a magnetic field, and a changing magnetic field can induce an electric current.

Front

What is the unit of measurement for magnetic field strength?

Back

The unit of measurement for magnetic field strength is the Tesla (T).

Front

What is the Earth's magnetic field?

Back

The Earth's magnetic field is a magnetic field that extends from the Earth's interior out into space, protecting the planet from solar wind.
