Antimagnetic watch. Anti-magnetic (non-magnetic) watches are those that are able to run with minimal deviation when exposed to a certain level of magnetic field. The International Organization for Standardization issued a standard for magnetic-resistant watches, which many countries have adopted.
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.
The gauss is the unit of magnetic flux density B in the system of Gaussian units and is equal to Mx /cm 2 or g / Bi /s 2, while the oersted is the unit of H -field. One tesla (T) corresponds to 10 4 gauss, and one ampere (A) per metre corresponds to 4π × 10 −3 oersted. The units for magnetic flux Φ, which is the integral of magnetic B ...
Definition. Cassette tape label with coercivity (a measure of the external magnetic flux required to magnetize the tape) measured in oersteds. The oersted is defined as a dyne per unit pole. [clarification needed][6] The oersted is 1000 4π (≈79.5775) amperes per meter, in terms of SI units. [7][8][9][10] The H-field strength inside a ...
An explosively pumped flux compression generator (EPFCG) is a device used to generate a high-power electromagnetic pulse by compressing magnetic flux using high explosive. An EPFCG only ever generates a single pulse as the device is physically destroyed during operation. They require a starting current pulse to operate, usually supplied by ...
Force between magnets. Magnets exert forces and torques on each other through the interaction of their magnetic fields. The forces of attraction and repulsion are a result of these interactions. The magnetic field of each magnet is due to microscopic currents of electrically charged electrons orbiting nuclei and the intrinsic magnetism of ...
