Magnetic metals include iron, cobalt, nickel, and their alloys. Learn which metals are magnetic and how their atomic structure creates strong magnetism.

Alnico Magnets offer high heat resistance and corrosion protection, while neodymium provides stronger pull. Compare their uses, strengths, and durability.

A magnetic compass uses a magnetized needle that aligns with Earth's magnetic field, reliably pointing north for navigation without electronics.

An N52 magnet hold varies by size—small ones support 4 lbs, while large N52 magnets can hold over 200 lbs. Check specs for exact weight capacity.

Neodymium magnets are expensive due to rare materials, complex manufacturing, high demand, and recycling challenges.

Earth is considered a giant magnet because its molten iron core generates a magnetic field, creating poles and a shield vital for life and navigation.

Gs mean gauss in magnets, indicating magnetic field strength. Gauss helps compare magnet power for electronics, science, and everyday use.

Alnico magnets offer heat resistance and durability but cost more, are brittle, and have lower strength than neodymium magnets.

An alnico magnet is a durable, heat-resistant magnet made from aluminum, nickel, and cobalt, used in sensors, motors, and scientific devices.

Nickel is magnetic due to its ferromagnetic properties, but not all nickel items or coins are magnetic depending on their composition and alloy mix.
