WebExplain : some details. The magnetic field is described mathematically as a vector field. This vector field can be plotted directly as a set of many vectors drawn on a grid. Each vector points in the direction that a compass would point and has length dependent on the strength of the magnetic force. Explain compasses.

WebA magnet is any object that can attract other materials with magnetic properties through a magnetic force. Every magnet has a north pole and a south pole. Either pole will attract iron. The direction of magnetic force between two magnets depends on how the poles are oriented. Opposite poles attract. Like poles repel.

WebMagnets are objects, which can attract, or pull, on some metals, like iron and steel. If you rub a piece of steel with a strong magnet, the piece of steel will become a magnet too. It has become magnetized. Other metals, like copper or gold, are not attracted to magnets. Magnets can also attract each…
