is the average magnetic path length = 0.94 (constant value) m {\displaystyle m~} is the mass of the sample in kilograms If all conditions are as defined in the standard, the standard deviation of the reproducibility of the values is not greater than 1.5% up to 1.5 T [ clarification needed ] for non-oriented electrical steel and up to 1.7 T for ...
Flux distribution for a flat refrigerator magnet Schematic diagram of a free-electron laser. Scaling up this design and adding a top sheet gives a wiggler magnet, used in synchrotrons and free-electron lasers. Wiggler magnets wiggle, or oscillate, an electron beam perpendicular to the magnetic field.
Magnetic field viewing film is used to show stationary or (less often) slowly changing magnetic fields; it shows their location and direction. It is a translucent thin flexible sheet, coated with micro-capsules containing nickel flakes suspended in oil. [ 1 ]
Magnetic induction B (also known as magnetic flux density) has the SI unit tesla [T or Wb/m 2]. [1] One tesla is equal to 10 4 gauss. Magnetic field drops off as the inverse cube of the distance ( 1 / distance 3 ) from a dipole source. Energy required to produce laboratory magnetic fields increases with the square of magnetic field. [2]

A plastic magnet is a non-metallic magnet made from an organic polymer. Plastic magnets could be used in computer hardware such as disc drives , as well as in medical devices such as pacemakers and cochlear implants , where the organic material is more likely to be biocompatible than its metallic counterparts.
