Permanent magnets contain a current-carrying wire.
Some minerals contain magnetite, which is atracted to magnets.
Man-made or Synthetic magnets are stronger than natural magnets and have many uses including alternative medicine (magnet therapy for Arthritis & Rheumatism), fridge/car magnets, they are also widely used in manufacturing. Made from a Nickle, Aluminium and cobalt (AlNiCo) compound they are magnetized by placing them in a machine which produces a strong electromagnetic field.

All electric motors contain magnets- and information storage in computers is based on magnets. Electrical generators contain magnets, as do electrical transformers. Even the charger for your IPod is based on electromagnets.
since magnets are all ready magnetised when found in nature called natural magnet artificial magnets that are made by man are called artificial magnets
