Magnetic force

Back

Magnetic force is the force exerted between magnets or between a magnet and a magnetic material.

Front

What are magnetic poles?

Back

Regions on a magnet where the magnetic force is concentrated.

Front

What will happen when similar magnetic poles are brought close to each other?

Back

The force pairs between the magnets become repulsive (push)

Front

What will happen when opposite magnetic poles are brought close to each other?

Back

The force pairs between the magnets become attractive (pull)

Front

What do the lines around this magnet represent?

Back

Magnetic Field

Front

What device is made of coils of wire that are connected to a battery in order to generate a magnetic field?

Back

Electromagnet

Front

How do the forces between magnets become repulsive/attractive when we flip the magnets to face similar/opposite poles?

Back

The shape of the magnetic field between them changes.

Front

If there is no permanent magnet in the doorbell, just metal like iron, then when we bring a magnet near the system we will observe...

Back

pulls no matter which direction the magnet is facing.
