Measuring the Strength of Magnets

Magnet Strength

We all know that there are different kinds of magnets—the magnet holding up your grocery list on your fridge isn’t in the same realm as the one being used to lift cars in the junkyard. So, how do we measure the strength of each of these different kinds of magnets?

Gauss

Carl Friedrich Gauss, considered to be one of the greatest mathematicians of all time, was a pioneer in the study of magnetic fields. Gauss was the first to create a device capable of measuring the strength and direction of a magnetic field. He was also responsible for developing a method for measuring magnetism. In honor of Gauss, the modern unit of magnetic flux density or magnetic induction was named for him.

The gauss meter is our modern version of Gauss’s magnetometer. A gauss meter is comprised of a gauss probe, the meter itself, and a cable to connect them. The meter functions on the Hall Effect discovered in 1879 by Edwin Hall. Gauss meters are used to measure small and relatively weak magnetic fields. When you need to measure a larger and more powerful magnetic field, you’ll need a teslameter.

Tesla

One tesla unit is equal to 10⁴ gauss and is a unit of magnetic induction or magnetic flux density in the metre–kilogram–second system (SI) of physical units. The tesla was named for Nikola Tesla in honor of all of his momentous contributions to science and the field of magnetism specifically.

Using Apex Magnets

At Apex Magnets, we measure our magnets based on pull strength or the amount of weight they’re able to pull on their own. Our magnets range in strength from less than a pound to upwards of 700 lbs!
