Alnico magnets: These were developed in the 1930s and are made from aluminum, nickel and cobalt. They're stronger than ceramic magnets, but not as strong as the ones that incorporate a class of elements known as rare-earth metals. Neodymium magnets: These contain iron, boron and the rare-...
Promoted by Coors Light Less than 1 percent of rare earth magnets that are used in everyday tools are recycled. Scott Dunn, CEO of the Urban Mining Company, believes reusing these rare magnets are critical to a cleaner future. For more videos, subscribe toMashable:http://on.mash.to/subscri...
Rare-earth magnets (these are strong magnets that will hold your keys securely) Drill (to make recesses for the magnets) Glue (to secure the magnets in place if needed) Follow the instructions for installing the magnets into the wood, and ensure they are flush with the surface to make a ...

PROBLEM TO BE SOLVED: To provide a method for recycling a heavy rare earth element capable of efficiently recycling a rare heavy rare earth element in the form of an alloy close to a product, and a method for recycling a rare earth magnet using an alloy obtained by the recycling method. ...
Join the battery and a strong magnet with the other rubber band so the magnet faces in the same direction as the cradle.The polarity of the magnet is unimportant. Step 5 Test the motor by placing the loop assembly into the cradle. If it works, it should spin. You may need to start ...
magnets that are commercially available. There are two main types of rare earth magnets: samarium–cobalt (Sm–Co) magnets and neodymium–iron–boron (Nd–Fe–B) magnets. The market is currently dominated by Nd–Fe–B magnets (> 95%). The magnetic field produced by Nd–Fe–B magnets can...
On the other hand, rare earth permanent magnets (PMs), like NdFeB, generate a low-cost and strong magnetic field. Thus, they are studied for attracting or steering magnetic nanoparticles too [15,34,35]. However, permanent magnets have the disadvantage that their magnetic field can only be ...
I already have 1/4" rare earth magnets in the corners of my larger models to keep them in place on a metal sheet for transport, you could probably do the same for the extra stability on larger metal models. One question: do you find the need to actually place the metal sheets in mov...
This condition occurs in Iron, Cobalt, Nickel and rare-earth groups. We can go one level deeper into quantum mechanics. This is where we ask, "What is the magnetic field made of?" Today, there are four basic forces that are known: gravity, electromagnetism, weak, strong. What creates ...
