What is Tesla?
Tesla is a unit to measure the magnetic field force. Its symbol is T. The unit is named after the famous inventor Nikola Tesla, who discovered an alternating current, among hundreds of other phenomena. The magnetic field of one Tesla is about 30,000 times stronger than the Earth's magnetic field. However, since the amount of Teslas is calculated by dividing the total magnetic flow (power) according to the area, the magnetic fields of the high tesla can be achieved by concentrating in a small space. Newton - the power needed to accelerate 1 kg at one meter per second to the other - is a lot of force for the magnetic field and is not easily achieved. The most powerful superconducting electromagnets produce only magnetic fields around 20t.
The most powerful continuous magnetic field has so far generated 45T measurements, and the strongest destructive pulse magnet about 850T. Gauss, another unit for measurement of magnetism, is 1/10 000. Tesla. Gamma, another unit used in Geofyiics to measure magnetic fields is one billion Tesla.
and Weber, another SI unit is used to measure magnetic flow, while Tesla is used to measure the density of magnetic flow, commonly understood as a magnetic field. It is possible for the material to be fully saturated with a magnetic flow. For example, 10 Teslas are considered to be the upper limit of the magnets of the Niobium-Titan accelerator.
Medical magnetic resonance imaging usually maintains 2T field strength. The large speaker magnet generates 1T. Exotic cosmic objects such as Magnetar, a neutron star with a massive magnetic field, produce between 0.1 and 100 gigates. This is enough to erase the credit card on the equivalent of the distance gap between the ground and the sun.
