Reversing the current flow effectively swaps the poles, changing which end attracts or repels. Permanent magnets, such as those made from alloys of iron, nickel, or cobalt, exhibit a fixed polarity derived from the alignment of their internal atomic structure.

These distinct points dictate how the magnet interacts with its environment and other magnetic objects, establishing a directional field that is invisible yet powerfully influential. This dynamic capability is crucial for devices such as relays and solenoids, where the controlled switching of magnetic poles is used to perform mechanical work.
Natural and Permanent Magnets While artificial electromagnets offer controllable polarity, the Earth itself acts as a massive natural magnet with its own north and south magnetic poles. This field is often illustrated using iron filings or vector diagrams that show lines of force.
Visualizing Magnetic Fields with Vector Diagrams
Understanding the specific characteristics of each pole is essential for grasping the fundamental laws of magnetism. Polarity in Current Flow Within an electromagnet, the designation of the north and south pole is determined by the direction of the electric current flowing through the coil of wire.
