Yes, nickel (Ni) is magnetic - it is one of the few elements that are ferromagnetic at room temperature.
🧲 Magnetic Properties of Nickel:
Type: Ferromagnetic
Curie Temperature: ~358 °C (676 °F or 631 K)
Behavior:
Below 358 °C: Strongly attracted to magnets; can be magnetized.
Above 358 °C: Becomes paramagnetic (loses permanent magnetism but still responds weakly to magnetic fields).
✅ Why Nickel is Magnetic:
It has unpaired electrons in the 3d orbital, allowing its atomic magnetic moments to align in the same direction, resulting in net magnetism.
Nickel is often used in:
Magnets and coinage
Alloys like stainless steel
Magnetic shielding and sensors

🧠 Key Insights:
Iron has the strongest magnetic response and is widely used in core electrical components.
Nickel is magnetic but with a lower Curie temperature, meaning it loses magnetism sooner when heated.
Cobalt has the highest Curie temperature, making it suitable for high-temperature magnetic applications.
