Magnetic Fields

A magnetic field is an invisible field around a magnet where magnetic forces can be felt. It is created by moving electric charges or by magnetic materials.

They repel each other and move away from each other.

They attract each other and move towards each other.

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

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

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

The strength of the magnetic force decreases as the distance between the magnets increases.

Magnetic fields interact with electric currents to produce motion in electric motors.

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

A magnetic field can be visualized using iron filings or by drawing field lines that show the direction and strength of the field.
