A brief history of Ampere`s law
... However, it did much more than explain the magnetic field between capacitor plates! The corrected form of Ampère’s law says that a changing electric field can create a changing magnetic field! It was already known from Faraday’s law (another of Maxwell’s four equations, v dφ E ...
