World Records

Always pushing the scientific envelope, the Magnet Lab holds numerous records for high magnetic fields and other key measures of the power and utility of the instruments at our facility.

Most of the records we have established since the lab opened have been short-lived, as we are constantly surpassing them. As you can see in the table below, where some of our current records are featured, there's a very good reason why hundreds of researchers a year travel to our unique lab to use these awesome tools. For technical details on these records, click on the blue links in the table.

First, a few quick definitions:

  • Dalton: Unit of molecular mass. A hydrogen atom weighs about 1 Dalton (Da)
  • Kelvin: A temperature scale used by scientists. Zero Kelvin (0 K) is known as absolute zero, and is the equivalent of -273 degrees Celsius and -460 degrees Fahrenheit. Absolute zero is as cold as cold can get.
  • Tesla: Measure of magnetic field strength. The Earth's magnetic field is one twenty thousandth (.00005) of a tesla (T).
