Acompass pointing north will point in a different direction when placed near a piece of metal. which causes this to happen?

magnetic fields
electromagnetism
electricity

magnetic fields

Explanation:

compass needle itself is a magnet . It aligns itself along the earth's magnetic fields to show north south direction. When some metal piece is put near a compass needle , it tends to attract the metal piece as metal is a magnetic material . So it gets deflected from its original orientation. So magnetic field around the needle is responsible for its deflection.

the arctic is a region of the planet, north of the arctic circle, and includes the arctic ocean, greenland, baffin island, other smaller northern islands, and the far northern parts of europe, russia (siberia), alaska and canada.
