Tesla is International System of Units in Magnetic induction Units of. It is abbreviated as Te, and the symbol is T. With 1A Constant current The straight long conductor of is vertically placed in a uniform magnetic field. If the conductor is subjected to a force of 1N per meter of length, the magnetic induction intensity of the uniform magnetic field is defined as 1T [2]

The strongest non pulsating (continuous) magnet in the world is located in Tallahassee, Florida, USA.
  • The main magnetic resonance imaging magnets used in hospitals are usually 1.5T and 3T, up to 4T; Up to 7 T for (human) research purposes
  • The magnetic field intensity of sunspot is 10 T
  • The nuclear magnetic resonance main magnet in chemical research is usually 11.74 T; Achieved with superconducting magnet, the maximum magnetic field reaches 25 T
  • The strongest sustained magnetic field generated by human in the laboratory (the National High Magnetic Field Laboratory of Florida State University, located in Tallahassee, Florida, USA) is 45 T
  • The record of the instantaneous strongest magnetic field generated in the laboratory is 80 T (Osaka University),
  • The strongest artificial magnetic field is 2800 T (the explosion was generated in Sarov, Russia)
  • The magnetic field level on the neutron star is 1 to 100 trillion (10 six )Tesla (10 six T to 10 eight T)
  • The magnetic field level on the magnetostar is 0.1 to 100 gigahertz (10 nine )Tesla (10 eight T to 10 eleven T)
  • Theoretically, the maximum magnetic field of the neutron star is estimated to be 10 thirteen T。 [4]
