what is magnetic permeability
Answers
Explanation:
Magnetic Permeability is a term refers to the ability of a material to gain or maintain magnetism. When certain materials are placed in a magnetic field they become magnetized. For example, when you take a piece of iron and rub it on a substance already magnetized or a magnet, it will become magnetized and have a resulting magnetic field.
What is Magnetic Permeability?
Permeability is the measure of how a substance or material supports forming a magnetic field within itself. It is the amount of magnetization that the substance will adopt or obtain when inserted into an applied magnetic field The term was first introduced in the early fall of 1885 by Oliver Heaviside with the opposite quality of a substance being called magnetic reluctivity. The magnetic permeability of a substance is designated by the Greek letter, mu or (?) and is measured in henres per meter (H/M) and newtons per ampere squared. These measures are also used to represent the air in a vacuum which is called the magnetic constant and has a value of 4?×10?7 H/m that is approximately, 1.2566×10?6 H/m.
