An electric current through a wire wound into a coil creates a magnetic field through the center of the coil, due to Ampere''s circuital law. Coils are widely used in electronic components such as electromagnets, inductors, transformers, electric motors and generators. A coil without a magnetic core is called an "air core" coil. Adding a piece of ferromagnetic or ferrimagnetic material in the cente…
The reason why the total energy storage decreases with the increase of the air gap is that when the air gap increases, the permeability of the magnetic medium …

Magnetic permeability of the vacuum is denoted by;µ₀ and has value; µ₀=4π.10⁻⁷Wb./Amps.m. We find the permeability of the matter by following formula; µ= B/H where; H is the magnetic field strength and B is the flux density. Relative permeability is the ratio of a specific medium permeability to the permeability of vacuum. µr=µ/µo
Diamagnetic materials: These materials have a magnetic permeability slightly less than that of free space. When exposed to an external magnetic field, they generate an opposing magnetic field, causing a small decrease in the net magnetic field. Examples include copper, gold, and bismuth. Ferromagnetic materials: These materials have a much ...

Materials with a high relative magnetic permeability like steel alloys containing combinations of cobalt, nickel, aluminum, tungsten, and silicon are used to guide the magnetic flux into a region to achieve high energy densities. These are ferromagnetic materials and have a permeability much higher than air.
The magnetic anisotropy and permeability values were estimated using coercivity and magnetization parameters in the corresponding relations. The higher magnetic permeability (547) and lowest anisotropy (11,100) were observed for the samples x + y + z = 0.45 and 0.6, respectively.
In electromagnetism, the absolute permittivity, often simply called permittivity and denoted by the Greek letter ε (), is a measure of the electric polarizability of a dielectric material. A material with high permittivity polarizes more in response to an applied electric field than a material with low permittivity, thereby storing more energy in the material.
With a high permeability core material, energy storage is minimal. In an inductor, the core provides the flux linkage path between the circuit winding and a non-magnetic gap, …
Explanation: Relative permeability=1+Magnetic susceptibility Since both paramagnetic and ferromagnetic materials have positive susceptibility, their relative permeability is greater than unity i.e. their permeability is more than the permeability of free space.
