May 23, 2025 · At its core, magnetism is a force—a special kind of interaction between objects that can cause attraction or repulsion without physical contact. Magnets produce magnetic …

Magnetism is a subject that includes the properties of magnets, the effect of the magnetic force on moving charges and currents, and the creation of magnetic fields by currents.

Fridge magnets, compass needles and some door fasteners are all examples of permanent magnets. Their magnetism comes from the "spin" of electrons. This isn't like the spinning of a …

Magnetism is a fascinating force. Understanding the different types and strengths of magnetic fields guides numerous technologies around us.

When most people think of magnetism, they think about the magnetic force experienced between two magnets. The magnetic force is caused by the magnet’s magnetic field and points in the …

Magnetism is the class of physical attributes that occur through a magnetic field, which allows objects to attract or repel each other. Because both electric currents and magnetic moments of …

May 21, 2025 · Discover what a magnetic field is, how it works, and why it matters — from Earth's protective shield to advanced technologies like MRI, power generation, and quantum computing.

Magnets work because of magnetic fields which arise from the motion of electric charges. This field exerts forces on other magnetic objects and moving charges, causing attraction or repulsion.
