Faraday was the first to publish the results of his experiments. [5] [6] Faraday's 1831 demonstration [7] Faraday's notebook on August 29, 1831 [8] describes an experimental demonstration of electromagnetic induction (see figure) [9] that wraps two wires around opposite sides of an iron ring (like a modern toroidal transformer).
Ørsted experiment (1820): Hans Christian Ørsted demonstrates the connection of electricity and magnetism by experiments involving a compass and electric circuits. Discovery of electromagnetic induction (1831): Michael Faraday discovers magnetic induction in an experiment with a closed ring of soft iron, with two windings of wire.
Electromagnetic or magnetic induction is the production of an electromotive force (emf) across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction .
The resistance of a thin Permalloy film is shown here as a function of the angle of an applied external field. Thomson's experiments [ 4 ] are an example of AMR, [ 7 ] a property of a material in which a dependence of electrical resistance on the angle between the direction of electric current and direction of magnetization is observed.

The quantum Hall effect (or integer quantum Hall effect) is a quantized version of the Hall effect which is observed in two-dimensional electron systems subjected to low temperatures and strong magnetic fields, in which the Hall resistance R xy exhibits steps that take on the quantized values
The existence of electromagnetic radiation was proved by Heinrich Hertz in a series of experiments ranging from 1886 to 1889 in which he discovered the existence of radio waves. The full electromagnetic spectrum (in order of increasing frequency) consists of radio waves, microwaves , infrared radiation , visible light , ultraviolet light , X ...
A lunar magnetometer experiment had a number of requirements that shaped its capabilities. The instrument needed to be able to operate during the lunar night since it was believed the collection of data from a full lunar rotation would be required. The instrument also needed to be able to perform its own self-calibrations on a regular cadence ...
