MAGNETS, MAGNETS and MORE MAGNETS

Front

What is a magnet?

Back

A magnet is an object that produces a magnetic field, which can attract or repel certain materials, typically metals like iron.

What are the two types of magnets?

Back

The two types of magnets are permanent magnets, which maintain their magnetic properties, and temporary magnets, which only exhibit magnetism when in a magnetic field.

Front

What is magnetic force?

Back

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

What is the difference between kinetic energy and potential energy?

Back

Kinetic energy is the energy of an object in motion, while potential energy is stored energy based on an object's position or state.

Front

What is the principle of magnetic attraction?

Back

Magnetic attraction occurs when opposite poles of magnets (north and south) come close to each other, pulling them together.

What is the principle of magnetic repulsion?

Back

Magnetic repulsion occurs when like poles of magnets (north-north or south-south) come close to each other, pushing them apart.

What is the role of magnetic fields?

Back

Magnetic fields are regions around a magnet where magnetic forces can be detected, influencing the behavior of other magnets and magnetic materials.

How do magnets affect electric currents?

Back

Magnets can induce electric currents in conductors through electromagnetic induction, which is the principle behind generators and transformers.

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 and cosmic radiation.

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.
