Who or what is Tesla?
The tesla is an SI unit for measuring the strength of a magnetic field and is abbreviated with the symbol (T) in physics. The unit is named after the famous inventor Nikola Tesla, who, among hundreds of other phenomena, also discovered alternating current. A magnetic field of one tesla, for example, is about 30,000 times as strong as the Earth's magnetic field, whereas magnetic resonance imaging typically reaches a field strength of 2 tesla. Exotic cosmic objects such as a magnetar, which is a neutron star with a massive magnetic field, produce between 0.1 and 100 gigatesla.
