	The magnetic field produced by a spinning disk was discovered by Francois Arago in 1824. Arago rapidly rotated disks made of conductive material beneath a magnetized needle, and the needle reacted to the magnetic field being produced by the disk. At the time, the phenomenon was difficult to explain. Later on, Michael Faraday wrote the theory of electromagnetic induction, which explained ~~how~~ Arago's rotations ~~worked~~.		The magnetic field produced by a spinning disk was discovered by Francois Arago in 1824. Arago rapidly rotated disks made of conductive material beneath a magnetized needle, and the needle reacted to the magnetic field being produced by the disk. At the time, the phenomenon was difficult to explain. Several scientists investigated Arago's rotations including Joseph Louis Gay-Lussac, Peter Barlow, Charles Babbage, and John Frederick William Herschel. Babbage and Herschel worked together to conduct experiments that tested the phenomenon on different materials, both conductive and non-conductive, and with different sizes of disks and needles. They found that Arago's rotations only worked with a big enough needle and a conductive disk. Later on, Michael Faraday wrote the theory of electromagnetic induction, which explained that Arago's rotations were the product of the disk be an inducted magnet that produced a magnetic field that influenced the magnetic needle above it.

	~~::'''Insert Connectedness Section here'~~''		1. Arago's Rotations utilize the Lorentz force created by a spinning conductive disk. Induction motors are based on Arago's Rotations and are cheaper to produce than
			synchronous motors because they do not require permanent magnets.

			2. The calculation of the magnetic field produced by a spinning disk requires the use of Calculus, which is a is a large branch of Mathematics.

			3. Neodymium disk magnets are used in products that require strong permanent magnets like wind turbines, sensors, speakers, alarms, and more.

	==Main Idea==		==Main Idea==
	~~Through~~ this page, ~~you~~ will ~~understand~~ how to solve for the magnetic field produced by a rotating, charged, circular disk.		On this page, we will explore how to solve for the magnetic field produced by a rotating, charged, circular disk.

	First, let us start with the basics. We know that moving charges spread out over the surface of an object will produce a magnetic field. This is similar to the concept of how charges spread out over an object ~~allowed them to~~ produce unique electric fields.		First, let us start with the basics.
