His namesake effect describes the rotation of polarized light by a magnetic field, and he also lends his name to the SI unit of a property which, for a sphere, is given by 4 pi times the permittivity of free space times the sphere's radius.  
One of this man's eponymous laws states that the first, second, and third components of the 4-gradient of the dual tensor vanish.  His namesake effect describes the rotation of polarized light by a magnetic field, and he also lends his name to the SI unit of a property which, for a sphere, is given by 4 pi times the permittivity of free space times the sphere's radius.  His eponymous law relating the curl of the electric field and the time derivative of the magnetic field was inspired by his experiments with a loop of wire and an electromagnet which showed that any change in the magnetic flux produces an emf.  FTP identify this namesake of the SI unit of capacitance who enunciated his eponymous law of induction.
