Large rare earth metals like magnetite, moissanite, iron ore and sulfur will be the building blocks of modern day magnets. Because these alloys are so valuable, they are protected by strict federal regulations. It can be very dangerous for a individual to walk into a magnet shop and get a hold of rare earth metal, without knowing and understanding how the process works. This is why it is important to research large rare earth magnets before you make the purchase, so you don’t set yourself up for large legal problems if your magnets don’t work as you expected.
Larger rare earth metals such as magnetite possess a magnetic force much stronger than small magnets would be capable of generating. But, they’re also quite hard to design and construct in a way that would give the desired results. Additionally, the potency of their magnetic force is only within a very small range, in comparison to other kinds of magnets. This is the reason it would be best to use small, lightweight, disposable items such as barbells, balls or even golf clubs as part of your own safe, portable home construction projects.
On account of the extreme sensitivity of these tiny magnets involved, there’s a good amount of wasted energy made by the conversion of electric current to magnetic field energy. This energy is usually wasted since there’s absolutely no way to get the magnets close to a conductive piece of alloy to produce a stable magnetic field. When trying to design big magnets, it would be far better to use lightweight, disposable items such as PVC pipes, PVC mats, or similar substances that can be used as temporary shields until you’re ready to make your large permanent magnet. Then, when you’re all set to build a large permanent magnet, then the simplest way to do so is to just drill holes into those PVC pipes or mats, place the magnetized piece of steel on top of the pit, then bolt the magnetized piece of steel onto the PVC tube or mat. The end result will be an extremely strong and durable portable magnetic field which will protect any system that’s set in its perimeter.https://www.youtube.com/embed/yM4Xe2c0B8M
