Strong magnets have been an important part of our lives since before recorded history. From the huge ironworks of our early America to the tiny devices we have in our cell phones, powerful magnets have provided us with a myriad of useful technology. The strong and weak torsion spring employed in computer chips to help them store information and transfer them around without worry of damaging the circuits. Even the credit card has a tiny powerful magnet that helps to hold it upright in a wallet.
Although strong magnets are an ancient idea, they remain popular in contemporary society. 1 kind of powerful magnet that’s still being used frequently is a neodymium magnet. Neodymium magnets are produced from earth magnets, a rare metal that has many essential properties and is used in a variety of scientific applications. A typical strong magnet, rare earth magnets uses four strong magnets at a row to make a charge. Since it’s rare-earth steel, the strength of a magnet made from neodymium is greater than strong magnets made from the far more common copper.
Due to their strength, neodymium magnets are the most powerful known magnets. Another variation of a solid magnet is a hypermagnetic magnet, that creates a relative magnetic field even when the magnets are not directly confronted daily. Hypermagnetic magnets can also be manufactured from earth magnets and make a strong magnetic field by trapping two reverse magnets with reverse repulsion. These strong magnets can be far more powerful than a leash magnet but have a tendency to ruin electric circuit boards by colliding with the conducting material. This is only one of the reasons why the strong magnets and hypermagnetic magnets are so helpful.
