10 Things You Need To Know About Magnets

Brief Description:

The modern world has seen the rise and fall of various companies that manufacture a wide variety of products ranging from electrical appliances to car air conditioning systems. One of these companies is magnetics, which provides various types of magnetic materials such as a solenoid, iron, steel, carbon, aluminum, etc., for various needs of people. These materials have been widely used in household things and many other fields such as medicine, aerospace engineering, space exploration, medical care, education, business, and manufacturing. With increasing market opportunities, magnets are being heavily used by most companies. In addition to the uses mentioned above, there are also two more possible markets for magnetic materials. Some of them are commercial use and others are industrial uses. Here I will share with you everything you need to know about magnetics and their applications. Read on.

What Are Magnetics?

Magnetics is anything that contains one or more metal particles. The best-known example of this is iron oxide which makes up about 90% of your body and an additional 4% of oxygen. This mineral is abundant in Earth’s upper mantle. There are also several minerals like selenium and boron that makeup approximately 5% of Earth’s surface. Rare-earth elements make up roughly 40% of the Earth’s surface.

Lanthanum occurs naturally only in crystalline phases, and only in minerals formed from neodymium and strontium. It is highly reactive and forms a very strong magnet. Generators and motors contain a number of rare earth elements.  All rare-earth elements are included in some form of technology which means that anyone can use them. However, because of their rareness, they are not easily available commercially in large quantities. Thus, there is much debate over what type of technology would be best. Currently, the first common way is to use it on computers and mobile phones. Other examples are using it in automobiles and even in submarines. In fact, rare-earth elements are actually used to make glass. As we know glass is not strong in itself, but when rare-earth elements are mixed in with it, it becomes very strong.

Most Magnetic Items That Use Metals

There are hundreds of items that use rare-earth elements. Some examples are cars, aircraft motors, telephones, microwaves, MRI scanners, military devices, computer monitors, television remote controls, and computer processors. A lot of these items use rare-earth elements to their full extent. For example, in vehicles, there are many types of magnets that use rare-earth elements, including solenoids, steels, and other magnets. Additionally, there are many types of consumer electronics too.


A common application of solid-state magnetic fields is in automotive or windmill components. Solid-state magnets typically operate on DC, AC, and VV (low frequency), with higher torque values between the brushes. Compared with the winding rotor, the solid-state current is more efficient now that we know that the winding rotor produces higher force at less weight while providing longer life, it looks like a good choice for an automotive vehicle. Solid-state currents have advantages like a smaller size, reduced maintenance requirements, and lesser wear and tear.

Casting Wire

Casting wire is one of the most popular ways to create a magnetic field. Wire casting requires either cast steel or cast iron, but cast iron is not as popular as cast steel.  Almost all old toys and kitchen utensils contain casting iron. But the thing is, casting iron is hard and requires special equipment and tools for it to work properly. Even so, casting iron is an easy way to make small components, and is certainly worth considering when trying to save money.

Cast Iron Magnet

Cast iron is much heavier than wrought iron or cast iron is. Consequently, it is much harder for children to hold the toy after getting it out of the box. Although there are exceptions to this, cast iron is a great alternative for making toys. Another advantage is, cast iron requires no special equipment or tools to use, whereas, wrought-iron requires special machinery to make a product, whereas, cast iron requires only regular empty paper. You don’t need any special chemicals to make cast iron; it only needs ordinary sandpaper, sanding cloths, and sharpening stone to cut straight into the material.

Cast Steel Magnet

Cast iron is the second type of magnet, as it is a solid-state magnet. What type of magnet does this mean? Well, a type of magnet called plate steel.
