Iron filings arrange in a pattern around a magnet because the magnet exerts a force in the region surrounding it. The force influences the iron filings, causing them to align in a particular pattern.

Like poles of magnets repel each other, while unlike poles attract.

The end of the compass needle pointing towards the north is called the north-seeking or north pole, while the end pointing towards the south is called the south-seeking or south pole. These ends approximately align with the north and south ...

Oersted’s research laid the groundwork for various technologies, including the radio, television, and fiber optics, showcasing the practical applications of his discoveries.

A deflected needle signifies that the electric current flowing through the copper wire has generated a magnetic effect.

The deflection of the needle demonstrates the interconnection between electricity and magnetism, indicating that these two phenomena are linked.

Hans Christian Oersted accidentally discovered that a compass needle deflected when an electric current passed through a nearby metallic wire.

Oersted demonstrated that electricity and magnetism are related phenomena, providing a crucial foundation for understanding electromagnetism.
