Magnetic Fields

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 field lines that show the direction and strength of the magnetic force.

Front

Can magnets interact without touching?

Back

Yes, magnets can exert forces on each other without direct contact, due to their magnetic fields.

Front

What happens when two north poles of a magnet are placed together?

Back

They repel each other.

Front

What happens when a north pole and a south pole of a magnet are placed together?

Back

They attract each other.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state, which can be converted into kinetic energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, dependent on its mass and velocity.

Front

What is the relationship between potential energy and kinetic energy?

Back

Potential energy can be converted into kinetic energy and vice versa, depending on the object's movement and position.

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; one is called the north pole and the other the south pole.

Front

What is the rule for magnetic poles?

Back

Like poles repel each other (north-north or south-south), while opposite poles attract each other (north-south).

Front

What is the unit of magnetic field strength?

Back

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