2. Electromagnetism - Wikipedia

   en.wikipedia.org/wiki/Electromagnetism

   Cover of A Treatise on Electricity and Magnetism. Electricity and magnetism were originally considered to be two separate forces. This view changed with the publication of James Clerk Maxwell's 1873 A Treatise on Electricity and Magnetism [6] in which the interactions of positive and negative charges were shown to be mediated by one force ...

   They are needed to convert high voltage mains electricity into low voltage electricity which can be safely used in homes. Maxwell's formulation of the law is given in the Maxwell–Faraday equation—the fourth and final of Maxwell's equations—which states that a time-varying magnetic field produces an electric field. The electromagnetic spectrum

4. Oersted's law - Wikipedia

   en.wikipedia.org/wiki/Oersted's_law

   Ørsted investigated and found the physical law describing the magnetic field, now known as Ørsted's law. Ørsted's discovery was the first connection found between electricity and magnetism, and the first of two laws that link the two; the other is Faraday's law of induction.

   Gauss's law for electric field is the dual of Gauss's law for magnetism. The electric potential is the dual of the magnetic potential. Permittivity is the dual of permeability. Electrostriction is the dual of magnetostriction. Piezoelectricity is the dual of piezomagnetism. Ferroelectricity is the dual of ferromagnetism.
