Such an altered coin is easily detected with a magnet. Because Ni keeps iron in the austenitic non ferromagnetic form. Is it becauses the Fe is not austenitic in permalloy? Or because there's enough Ni to overcome the austentic Fe? But I am not expert in metallurgy, relying on googled info and I do as well remember typical CrNi steel is not ferromagnetic.

Interestingly, I also found that austenitic alloys can be partly converted to ferromagnetic forms martensitic and ferritic using cold working the austentic crystal structure -- which Fe favors in the presence of Ni -- can be restored by melting and recooling.

Nickel is undoubtedly capable of collecting all 6 PGE elements from ores.

This metal along with its alloy is often used as catalysts for hydrogenation reactions. The use of nickel unintentionally started back in BCE but was often mistaken with ore of silver.

Originally the only source of nickel was the rare Kupfernickel. In the year , nickel was produced as a byproduct of cobalt-blue production. In , the first large-scale smelting of nickel began in Norway. Because of its resistance to corrosion, nickel was occasionally used as a substitute for decorative silver.

Some of the usages of nickel include coinage, rechargeable batteries, Alnico magnets, stainless steel, electric guitar strings, microphone capsules, plumbing fixtures. So we came to the conclusion that Nickel is a ferromagnetic substance. The main reason for its ferromagnetism is the presence of 2 unpaired electrons. The electrons align parallelly in presence of an external magnetic field. Nickel holds its magnetic property even after removal of the external magnetic field which makes it a permanent magnet.

So, guys, I tried to make you understand magnetism in nickel in detail. Let me know through your valuable comments if you have any queries related to it.

Believing they'd discovered another copper ore, the miners attempted to extract the copper, but, of course, the rocks failed to produce.

The frustrated miners blamed Nickel, a mischievous demon in German mythology, for playing a prank on them and began calling the ore kupfernickel , translated as "copper demon. About a century later, in , the Swedish alchemist Baron Axel Fredrik Cronstedt tried heating kupfernickel with charcoal and found that its various properties — such as being white and magnetic — clearly revealed that it wasn't copper.

Cronstedt is credited as the first person to extract nickel and isolate it as a new element. He dropped the name "kupfer" and called the new element nickel. Nickel is the fifth most abundant element on Earth. However, it is times more concentrated below the Earth's crust than in it, according to Chemicool. In fact, nickel is believed to be the second most abundant element in the Earth's inner core, with iron being the first by a large margin.

Nickel is typically found in two types of deposits: laterite deposits, which are the result of intensive weathering of surface nickel-rich rocks, and magmatic sulfide deposits. Nickel can also be found in manganese nodules and crusts on the deep sea floor, but currently these are not being mined, according to Geology. The main mineral sources of nickel are limonite, garnierite and pentlandite. In , Norway became the first large-scale nickel smelting site. Here they used a type of nickel ore known as pyrrhotite.

In , large deposits of nickel were discovered in the Sudbury Basin in Canada, which is where about 30 percent of the world's nickel is mined today. It is believed that this large deposit of nickel is due to an ancient meteor impact.
