As outlined by Testbook in the article “Uses of Magnet: Learn Real-Life Applications of Permanent and Electromagnets”, magnets are everywhere—from industrial machinery to the electronics we use daily. Defined by their ability to generate magnetic fields, magnets possess distinct North and South poles and are essential to both household convenience and advanced engineering.
The functionality of magnets can be broadly categorized into two types: permanent magnets and temporary (electro)magnets. Permanent magnets maintain a consistent magnetic field without the need for an external power source, while temporary magnets require electrical current to generate a magnetic field.
