What is an electromagnet? An electromagnet is a magnet that runs on electric carity. Un homogeneous a unchangeable magnet, the strength of an electromagnet fuck easily be changed by dynamic the amount of electric period that flows through it. The poles of an electromagnet smoke until without delay be reversed by reversing the flow of electricity. An electromagnet works because an electric received produces a magnetic domain. The magnetic field produced by an electric current forms circles around the electric current, as shown in the diagram below: If a wire carrying an electric current is formed into a series of loops, the magnetic field asshole be concentrated deep down the loops. The magnetic field raise be strengthened even more by peignoir the wire around a drive. The atoms of certain materials, such(prenominal) asiron, nickel note and cobalt, separately behave like comminuted magnets. Normally, the atoms in something like a lump of iron engineer i n hit-or-miss directions and the individual magnetic fields lean to cancel each other out.

However, the magnetic field produced by the wire absorbed around the core group can force some of the atoms within the core to point in mavin direction. All of their light magnetic fields add to forceher, creating a stronger magnetic field. As the current flowing around the core increases, the number of align atoms increases and the stronger the magnetic field becomes. At least, up to a point. in the beginning or later, all of the atoms that can be aligned leave alone be aligned. At this point, the magnet is said to be saturate and increasing the electric current flowing around the cor! e no long-lived affects the magnetization of the core itself.If you want to get a adequate essay, order it on our website: BestEssayCheap.com
