Relationship with CGS units
Examples of different magnetic flux densities in nature and in technology:
|10 −10 to 10 −8||Magnetic fields in the interstellar medium and around galaxies|
|5 · 10 −5||Earth's magnetic field in Germany|
|10 −4||Permissible limit value for electromagnetic fields at 50 Hz (household electricity) in Germany according to the 26th BImSchV|
|0.002||At a distance of 1 cm from a 100 A current, e.g. B. Battery current when starting a car, see Ampère's law|
|0.1||Commercially available horseshoe magnet|
|0.25||A typical sunspot|
|1.61||Maximum flux density of a NdFeB magnet (neodymium-iron-boron). Typically, the magnets are manufactured with flux densities between 1 T and 1.5 T. NdFeB magnets are currently the strongest permanent magnets|
|2.45||Saturation polarization of Fe 65 Co 35 , the highest value of a material at room temperature.|
|0.35 to 3.0||Magnetic resonance tomograph for use on humans. Devices with 7.0 T and more are also used for research purposes|
|8.6||Superconducting dipole magnets of the Large Hadron Collider at CERN in operation|
|25.9||Currently the strongest superconducting magnet in NMR spectroscopy (1.1 GHz spectrometer)|
|32||Strongest magnet based on (high temperature) superconductors|
|45.5||The most powerful permanent electromagnet, hybrid of superconducting and conventional electromagnets|
|100||Pulse coil - highest flux density without destroying the copper coil, generated for a few milliseconds|
|1200||Highest flux density generated by electromagnetic flux compression (controlled destruction of the arrangement, in the laboratory)|
|2800||Highest flux density generated by explosively driven flux compression (outdoors)|
|10 6 to 10 8||Magnetic field on a neutron star|
|10 8 to 10 11||Magnetic field on a magnetar|
