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 ...
Earth's magnetic field at 50° latitude. 10 −4 T. 100 μT. 1 G. Magnetic flux density that will induce an electromotive force of 10 -8 volts in each centimeter of a wire moving perpendicularly at 1 centimeter / second by definition (1 gauss = 1 maxwell / centimeter² ) [7] 500 μT. 5 G.
Certain diving watches produced by Sinn as mission timers (in German: "Einsatzzeitmesser") for professional users are also protected against magnetic fields up to 1,000 Gauss / 80,000 A/m, using a protective sheath consisting of a closed, magnetically soft inner case that includes the dial, the movement holding ring and the case back.

The shape of the magnetic fields of a permanent magnet and an electromagnet are revealed by the orientation of iron filings sprinkled on pieces of paper. A magnetic field (sometimes called B-field[1]) is a physical field that describes the magnetic influence on moving electric charges, electric currents, [2]: ch1 [3] and magnetic materials.
e. In physics, Gauss's law for magnetism is one of the four Maxwell's equations that underlie classical electrodynamics. It states that the magnetic field B has divergence equal to zero, [1] in other words, that it is a solenoidal vector field. It is equivalent to the statement that magnetic monopoles do not exist. [2]
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 ...
