The Science Behind Strong Magnets

Strong magnets have an important job in our modern world: they hold the many elements together that make up a solid, moving part of any object. While strong magnets are essential for holding together the different pieces of heavy metal and plastic that make up a car, for example, they’re also responsible for holding the many pieces of iron that constitute a table or a piano. They’re responsible for holding the separate pieces of wood together to form a nice, solid structure that makes it possible to write a song or play a musical instrument. Strong magnets don’t just hold things together: they also repel each other, which means that if you put a magnet on top of something that’s both heavy and unyielding, the repulsion between the magnets will cause the object to be repelled from the middle. (The repulsion force is actually much stronger than the attraction force, though: so strong that, in some situations, it may be able to move the object on its own.)

A rare-earth magnetic field is one of the strongest in the known universe. A neodymium magnet, which is a rare-earth magnetic field generator, is the most commonly used kind of strong magnetic generator today. For this reason, they are often found in mobile homes, RVs, campers, motorcycles, trucks, and boats. You may have even heard of someone with a generator built into their boat. Strong magnets aren’t only used for strong magnetic generators and for holding objects together: they’re also used in medical applications, such as when doctors apply magnets to the skin in hopes of healing damaged tissue.

There are a number of different ways that these unique magnets work, but all have one thing in common: a strong magnetic field is created by aligning the magnets in a way that creates a very strong magnetic field. This field is similar to the one created by the Earth’s magnetic field, which is why many people call the earth “magnetized.” (The term “high magnetic field” is actually an older term, dating back to the 1950s, which is why it’s becoming increasingly popular.)
