How Are Magnets Affected by Cold?

Cold weather is great for enjoying hot cocoa by a fireplace, college football, and white Christmases. But what does it do to magnets? As it turns out most magnets don’t mind the cold. In fact, some may perform better when the temperature drops. That’s because the atoms that comprise magnets vibrate...

Flipping Earth’s Magnetic Fields – in IMAX 3D

How’s this for the plot of a new disaster movie – the earth’s magnetic field begins to weaken, and then flips completely. The result? Flash floods, earthquakes, meteor showers and other natural and cosmic calamities, none of which prevent Tom Cruise from getting his family to safety. Title: Field...

Magnet Blog: How Magnetic Viewing Film Works

Magnetic viewing film (also called magnetic viewing paper) is made of millions of tiny magnetic flakes suspended in clear oil.  This oil is then sandwiched between two sheets of plastic.  The magnetic viewing film can then be used to "see" the pattern of magnetization. When a magnet is placed under...

Magnet Blog: Can You Really Erase Your Hard Drive With A Magnet

We are often asked if we sell magnets that will erase hard drives.  This is not one of our target applications, and most of our engineers report that they prefer a sledge hammer to a magnet when looking for external forces to disable the storage device.  Magnets often distort more than erase the...

Magnet Blog: Factors Which Cause Permanent Magnets to Lose Strength or to Demagnetize

You've asked, so we're answering: Magnetic domains locked in, result in the ability of a permanent magnet to support an external magnetic field.  Once established these domain positions are held until acted upon by forces exceeding those of the locked domains.  The energy required to change the...
