... deflected by an electric current in a nearby wire. In 1831, MICHAEL FARADAY showed that a changing magnetic field can induce a current in a circuit. In 1860, JAMES CLERK MAXWELL predicted that a changing electric field has an associated magnetic field and wrote the mathematical equations that descri ...

... ∂D/∂t, and so he reformulated Ampère’s law as ∇ ∇×H = J + ∂D/∂t. Maxwell’s equations are essential to the understanding of such things as the electrical and optical properties of matter, the ionosphere, ‘space weather’, solar dynamics and pulsars. New advances, the Large Hadron Collider, also depend ...

... Morley looked and looked, and decided it wasn’t there. How do waves travel??? Electricity and magnetism are “relative”: Whether charges move or not depends on which frame we use… This was how Einstein began thinking about his “theory of special relativity”… We’ll leave that theory for later…maybe. ...
