Magnetic Forces

Front

What is a magnetic force?

Back

A magnetic force is the attraction or repulsion that arises between electrically charged particles due to their motion. It is a fundamental force that acts at a distance.

Front

What are the two types of magnetic poles?

Back

The two types of magnetic poles are North and South. Like poles repel each other, while opposite poles attract.

Front

What happens when like magnetic poles are brought together?

Back

Like magnetic poles repel each other.

Front

What happens when opposite magnetic poles are brought together?

Back

Opposite magnetic poles attract each other.

Front

What is the magnetic field?

Back

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

Front

How can you visualize magnetic field lines?

Back

Magnetic field lines can be visualized using iron filings sprinkled around a magnet. The filings align along the field lines, showing the direction of the magnetic field.

Front

What is the relationship between electricity and magnetism?

Back

Electricity and magnetism are interconnected; an electric current produces a magnetic field, and a changing magnetic field can induce an electric current.

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. It can be turned on and off.

Front

What is the right-hand rule in magnetism?

Back

The right-hand rule is a method used to determine the direction of the magnetic force, magnetic field, or current. If you point your thumb in the direction of the current, your fingers curl in the direction of the magnetic field.

Front

What is magnetic induction?

Back

Magnetic induction is the process by which a material becomes magnetized when exposed to a magnetic field.
