There’s a high chance that you know a thing or two about magnets. We come into contact with these materials multiple times in the course of our daily lives. The three categories of magnets are permanent, temporary, and electromagnet. The materials are grouped depending on their source of magnetism. The list of elements in these groups includes neodymium magnets, ferrite magnets, ndfeb magnets, among others.
They all play crucial roles in various gadgets and pieces of equipment. Some devices that use magnets include credit cards, toys, MRI machines, business tools, and toys, to mention a few. They differ in size, making some plainly visible and others out of sight. Below is a list of things that depend on the use of magnets.
Electronics & Computers
Numerous gadgets, such as computers, depend on magnets to store data on hard drives. Magnets change the path of magnetic materials on hard disks in fragments that later represent computer data. Next, the devices read the direction of each portion of the magnetic material to interpret the information. Speakers found in televisions, radios, and other gadgets use magnets as well. A magnet and wire coil convert electronic signals into sound vibrations.
The industrial world is one of the many sectors that use magnets for numerous reasons. For instance, the magnet in an electric generator converts mechanical energy into electricity. In other cases, some motors turn the magnetic energy back into mechanical power. Mines utilize magnetic sorting to separate crushed rocks from handy metallic ores. In recycling, electromagnets in cranes pick up and move vast pieces of metals which can weigh several kilograms.
Health & Medicine
One of the most common devices in the medical sector that uses magnets is the Magnetic Resonance Imaging (MRI) machine. The machine uses strong magnetic fields to produce a radar-like radio signal from within the body. The signal is then utilized to create a detailed diagram of organs, bones, and other tissues. Compared to the magnets in our homes, MRI magnets are powerful. Also, magnets are used by hospitals in tackling cancer. A professional will inject a fluid sensitive to magnets into the affected area. A powerful magnet is later used to create heat in the body, destroying the cancer cells minus harming normal organs.
Several gadgets and items depend on magnets to functions, as you can see from the information above. Also, in our homes, one of the most common uses is keeping refrigerator doors shut and sticking reminder notes on the metal doors.
