Diamagnetism vs. Ferromagnetism: What's the Difference?
Diamagnetism is a weak, universal magnetic response repelling fields; ferromagnetism is a strong attraction creating permanent magnets.
Diamagnetism is a property of all materials, exhibiting a weak repulsion from magnetic fields. Ferromagnetism involves strong attraction, seen in materials like iron.
Diamagnetism results from changes in electron orbits under magnetic fields. Ferromagnetism arises from the alignment of electron spins.
In diamagnetism, the magnetic effect is usually temporary and weak. Ferromagnetism can lead to permanent magnetization.
Diamagnetism occurs in materials like copper and water. Ferromagnetism is found in elements like iron, cobalt, and nickel.
Diamagnetism is temperature-independent. Ferromagnetism often decreases with increasing temperature, losing magnetism above the Curie point.

Ferromagnetism allows steel to become a permanent magnet.
Of or relating to a substance that generates a magnetic field in the direction opposite to an externally applied magnetic field and is therefore repelled by it.
Of or characteristic of substances such as iron, nickel, or cobalt and various alloys that exhibit extremely high magnetic permeability, a characteristic saturation point, and magnetic hysteresis.
(physics) The phenomenon whereby certain substances can become permanent magnets when subjected to a magnetic field.
Phenomenon exhibited by materials like iron (nickel or cobalt) that become magnetized in a magnetic field and retain their magnetism when the field is removed
