Unlike alloys like alnico, the magnetism of electromagnets ceases as soon as the electricity stops flowing, which can be very handy for an array of the modern uses of magnets. What do we use magnets for? In the modern world, we use magnets in almost all aspects of our lives, from ourmo...
Magnets don't delete things from hard drives because hard drives themselves are generally made with powerful magnets inside of them. If you leave a strong electromagnet close to a hard drive, it could cause damage to the hard drive, but this rarely happens. Computer hard drives generally have ...
So, what can you possibly use ferrite magnets for? Uses of Ferrite Magnets Although ferrite magnets are not as strong as neodymium, you can use them for different functional things. You don’t need to add additional coatings or other treatments for them to work well. So, you can use them...
The most common magnetic metal is iron. It is the cheapest one with a price of $0.82 per ounce. Gold and Aluminum do not have magnetic properties, but you will notice that stainless steel can get attracted by magnets. In this article, we will also talk about other metals such as: Samar...
