FAQ
What happens if you cut a magnet in half?
You can think of a magnet as a bundle of tiny magnets, called magnetic domains, that are jammed together. Each one reinforces the magnetic fields of the others. Each one has a tiny north and south pole. If you cut one in half, the newly cut faces will become the new north or south poles of the smaller pieces.
How is magnet strength measured?
The intensity of a magnetic field, measured in Gauss or Teslas (10,000 Gauss = 1 Tesla), is also a common measurement of a magnets strength as this is a representation of the density of a magnetic field produced by a magnet, known as flux density.
What is magnet pull strength?
One method of determining the strength of a magnet is through pull strength. Pull strength is a reliable method of measuring the maximum strength, or holding power, that a magnet has before it is separated from ferrous material. It is measured in pounds or kilograms.
Why do magnets lose their magnetism when dropped?
Permanent magnets can lose their magnetism if they are dropped or banged on enough to bump their domains out of alignment. ... The reason that would be hard to bump a piece of iron and make it magnetic is because of the way vibrations propagate in the material.
Are larger magnets stronger?
Size is just one of the ways one can change the strength of a magnet. However, it can get very difficult and expensive to simply make a magnet bigger. ... By reducing the electrical resistance, much higher amounts of electrical current can be put through the magnets, thereby generating a much stronger magnetic force.
