The Difference Between Electromagnetism and Magnetism

Electromagnetism and magnetism are closely related but distinct concepts in physics. Magnetism refers to the force of attraction or repulsion between objects with magnetic properties, such as iron or certain alloys. On the other hand, electromagnetism involves the interaction between electric currents and magnetic fields.

In electromagnetism, an electric current creates a magnetic field, and a changing magnetic field can induce an electric current. This relationship is described by Maxwell's equations in the field of electromagnetism.

In conclusion, while magnetism deals with the inherent properties of magnetic materials, electromagnetism involves the interaction of electric currents and magnetic fields.
