The tesla (symbol T) is the SI derived unit o magnetic field strength or magnetic flux density, commonly denotit as B. Ane tesla is equal tae ane weber per square metre, an it wis defined in 1960[1] in honour o Nikola Tesla. The strangest fields encountered frae permanent magnets are frae Halbach spheres which can be ower 4.5 T.[2]
