What Is a Magnet?

A magnet is an object that produces a magnetic field, attracting certain metals like iron, cobalt, and nickel. I see magnets every day, from refrigerator magnets to powerful industrial devices. The most common types of magnets include permanent magnets, such as those found in household items, and electromagnets, which rely on electric current. Materials like iron, cobalt, nickel, and gadolinium show strong magnetic effects and are called ferromagnetic. When I place a magnet near an unmagnetized ferromagnetic material, it induces local magnetization, causing attraction.

• Permanent magnets: Used in everyday objects, like fridge magnets.
• Electromagnets: Found in motors, generators, and MRI machines.
• Ferromagnetic materials: Iron, cobalt, nickel, gadolinium.

Tip: Magnets play a key role in modern technology, from electric vehicles to medical devices.

How Magnets Work

Magnets generate magnetic fields through atomic alignment or electric current. Permanent magnets create magnetic fields because their atomic magnetic dipoles align, forming a strong field that extends into space. Electromagnets work differently. When electric current flows through a coil, it creates a magnetic field. I use permanent magnets for stable, long-lasting magnetism. Electromagnets offer flexibility, as I can turn them on or off by controlling the current.

• Permanent magnets: Atomic dipoles align, producing a constant field.
• Electromagnets: Electric current generates a controllable field.
