the element is cobalt
Alnico is an Alloy made of Aluminium, Nickel and Cobalt. Alnico is used to make Magnets.
Iron is used for electromagnets.
Alnico used for magnets is primarily iron, nickel, cobalt, and aluminum. Since it is magnetic, you know that there is iron in the alloy (~45% by weight). The name comes from the other elements that make up the alloy AlNiCo as in aluminum (Al), nickel (Ni), and cobalt (Co). Copper and titanium are present in much smaller quantities as well as other proprietary additions. Non-metals are present in the alloy like sulfur.The alnico quasicrystal is primarily aluminum nickel and cobalt. This alnico is not used for permanent magnets.
The term alnico is derived from the names of three metals, aluminum, nickel, and cobalt, which can be used to make an alloy that has useful magnetic properties. Ferrite is a form of iron. Alnico magnets are more powerful and more expensive than ferrite magnets.
False permanent magnets can but electromagnets need a running current A+
Several different metals can be used in magnets. Iron is perhaps the most common metal used in permanent magnets, but alloys such as Alnico (Aluminum, Nickel, and Cobalt) can also make very strong permanent magnets.
Most magnetic alloys are based on one or more of the following:ironnickelcobaltHigh field strength modern alloys also contain rare earth metals.
Ceramic magnets are made of ferrite material and are brittle but have good resistance to corrosion. They are relatively weak in magnetic strength but are cost-effective and widely used in applications like refrigerator magnets and speakers. Alnico magnets, on the other hand, are made of aluminum, nickel, and cobalt alloys and are stronger in magnetic strength but more expensive. They are used in applications requiring high temperature stability, such as sensors and electric motors.
I guess Al (aluminium), Ni (nickel) and Co (cobalt).
Alnico magnets: used in sensors, speakers, and electric motors. Ceramic magnets: used in educational kits, refrigerator magnets, and crafting. Neodymium magnets: used in headphones, wind turbines, and MRI machines. Samarium Cobalt magnets: used in aerospace applications, electric vehicles, and small motors. Flexible magnets: used in signage, refrigerator decorations, and craft projects.
Nickel is a ferromagnetic material, like iron and cobalt, so quite a few magnets have nickel in them. Nickel shows strong magnetic properties up to 355°C (671°F).Nickel is also a major constituent of Alnico, which is an alloy of Aluminum, Nickel and Cobalt. This alloy is widely used in magnets. Alnico magnets are found in industrial and consumer applications where strong permanent magnets are needed like in electric motors, guitar pickups, microphones, sensors, loudspeakers, etc.If not used directly in the magnet, Nickel is often used to plate magnets. Some common Nickel-plated magnets include Alnicos, Samarium Cobalt, and Neodymium Iron Boron
A magnet ie. the the ones on your fridge are made by manufactures pushing electrical current through ferrous metals causing them to have magnetic properties. Rare earth magnets are naturally occurring elements that have magnetic properties by themselves.
