RELATION BETWEEN ELECTRIC & MAGNETIC FIELDS James Clerk Maxwell (1831-1879) Familiar name to physicist- rank next to Newton & Einstein Maxwell’s equation-basis of field theory-involves extension of Faraday’s Laws & their interpretation into set of 4 complex mathematical equations Maxwell’s equations connected electricity & magnetism & also led to the theory of light, prediction of calculations was an accelerated charged particle would generate combined electrical & magnetic disturbances capable of traveling indefinitely through empty spaces ELECTROMAGNETIC WAVES SPEED=C=(frequency)(wave length) Range : heat, television, radio, radar, microwave, infrared visible, Ultraviolet, x-rays, gamma rays Creations: 3 wires: transmitter, receiver(antenna) Verified in 1887- Hertz (after the death of Maxwell) That electromagnetic waves exist and behave exactly as predicted Biography: born into old, distinguished Scottish family Mother died at his age of 8, raised by his father who mixed with distinguished scientific Circle (Edinburgh), given the best education at the age of 15 published 1st Paper with the Royal Society, graduated from college with honors & was appointed professor of natural philosophy at Cambridge 1871- First Cavendish professor of Physics (designed lab and Recruited staff)
