Electric current passing through a wire produces a magnetic field.

When electric current flows, the compass needle shows a change in direction.

A type of magnet where the magnetic field is produced by electric current.

Scientist who discovered the link between electricity and magnetism in 1820.

Unit of magnetic field strength named after Oersted.

A closed loop that allows electric current to flow.

A device that resists the flow of electric current, used to control current flow.

A region around a magnet where magnetic forces can be felt.

Phenomena that occur due to the interaction of electric currents and magnetic fields.

The change in direction of the compass needle due to magnetic influence.

Electric current creates a magnetic field around a wire.

Compass needle deflects when near an electric current.

Oersted found that current deflects a compass needle in 1820.

An electric circuit allows current to pass through a path.

Studies focused on the relationship between electricity and magnetism.

Electromagnets use current to create temporary magnetic fields.

Electromagnetic effects are vital for technology like radios and televisions.

Oersted's work laid the foundation for electromagnetism studies.

The oersted is a unit measuring magnetic field strength.

The needle responds to magnetic fields created by current.
