CHAMPVA is a Department of Veterans Affairs program; TRICARE is a regionally managed health care program for active duty and retired members of the uniformed services, their families, and survivors. In some cases a Veteran may appear to be eligible for both/either program on paper.
Quick Answer. Michael Faraday discovered the law of electromagnetic induction in 1831. He realized that current in a circuit can be induced by changing the magnetic field. Faraday tested it by wrapping a paper cylinder with a wire and connecting the coil to a galvanometer. Faraday then moved the magnet back and forth inside the cylinder.
Quizzes. Diamagnetic, Paramagnetic, and Ferromagnetic Materials. When a material is placed within a magnetic field, the magnetic forces of the material's electrons will be affected. This effect is known as Faraday's Law of Magnetic Induction.n diamagnetic materials all the electron are paired so there is no permanent net magnetic moment per atom. Diamagnetic properties arise from the realignment of the electron paths under the influence of an external magnetic field. Most elements in the periodic table, including copper, silver, and gold, are diamagnetic.
