What shape do the magnetic field lines of Earth resemble?

Back

The magnetic field lines of Earth resemble those of a bar magnet, emerging from the north pole and entering the south pole.

Front

How do magnetic field lines behave around a bar magnet?

Back

Magnetic field lines emerge from the north pole and curve around to enter the south pole.

Front

What is the significance of the north and south poles in magnets?

Back

All magnets have a north pole and a south pole, which are essential for their magnetic properties.

Front

What happens when like poles of magnets are brought together?

Back

Like poles (north-north or south-south) repel each other.

What happens when opposite poles of magnets are brought together?

Back

Opposite poles (north-south) attract each other.

Front

What is the definition of a magnetic field?

Back

A magnetic field is a region around a magnet where magnetic forces can be detected and where magnetic materials experience a force.

What is the role of magnetic fields in navigation?

Back

Magnetic fields are used in navigation systems, such as compasses, which align with Earth's magnetic field to indicate direction.

Front

What is the relationship between electric currents and magnetic fields?

Back

Electric currents produce magnetic fields, and this principle is the basis for electromagnetism.
