Answers and Solutions

Answer

Permeability is a constant of proportionality that exists between magnetic induction and magnetic field intensity. This constant is equal to approximately 1.257 x 10-6 henry per meter (H/m) in free space (a vacuum). In other materials it can be much different, often substantially greater than the free-space value, which is symbolized µo

Answer

permeability is the property of the material which supports the magnetic field lines to pass through it and is represented by miu.

Answer

Magnetic permeability (μ) is the ability of a magnetic material to support magnetic field development. In other words, magnetic permeability is the constant in the proportionality between magnetic induction and magnetic field intensity. The greater the magnetic permeability of the material, the greater the conductivity for magnetic lines of force, and vice versa. The magnetic permeability of a material indicates the ease with which an external magnetic field can create a higher magnetic force of attraction in the material. The SI unit of magnetic permeability is Henry per meter.

The Permeability of Free Space

The permeability of free space µ0 (the permeability constant or the magnetic constant) is

µ0 = 4π 10−7 (H/m)

    ≈ 1.257 10−6 (H/m, N/A2)

The Relative Permeability

The relative permeability is the ratio of the permeability of a specific medium to the permeability of free space µ0

µr = µ / µ0                                             (1)

where

µr = the relative permeability 

µ = permeability of the medium (H/m)

Answer

The ability of a substance to let another substance pass through it is called as Permeability. 

Answer

PERMEABILITY IS A PROPERTY OF ANY MATERIAL BY WHICH IT ALLOWS FLUID TO PASS THROUGH IT WITHOUT GETTING AFFECTED.PERMEABILITY ALLOWS POROUS ROCKS TO ALLOW WATER TO PASS THROUGH THEM TILL THEY REACH NON-POROUS ROCKS AND ARE STORED THERE AS GROUNDWATER.

Answer

Property of a material that lets fluids (such as water or water vapor) to diffuse through it to another medium without being chemically or physically affected. 

Answer

Answer

Ans: Permeability, also called magnetic permeability, is a constant of proportionality that exists between magnetic induction and magnetic field intensity. This constant is equal to approximately 1.257 x 10-6 henry per meter (H/m) in free space (a vacuum). In other materials it can be much different, often substantially greater than the free-space value, which is symbolized µo.

In engineering applications, permeability is often expressed in relative, rather than in absolute, terms. If µo represents the permeability of free space (that is, 1.257 x 10-6 H/m) and µ represents the permeability of the substance in question (also specified in henrys per meter), then the relative permeability, µr, is given by:

µr = µ / µo  = µ (7.958 x 105)

Answer

The strength of the material to prevent it from being magnetised is measured by its permeability. A permeable material can be easily magnetised and vice-versa.

Answer

In electromagnetism, permeability is the measure of the ability of a material to support the formation of a magnetic field within itself. Hence, it is the degree of magnetization that a material obtains in response to an applied magnetic field. Magnetic permeability is typically represented by the (italicized) Greek letter µ. The inverse of magnetic permeability is magnetic reluctance.

In SI units, permeability is measured in henries per meter (H/m or H·m−1)

Answer

• It is the property of any material or medium which allows the magnetic field to pass through it or it inicates the degree to which a material or medium can hold the magnetic field.
• higher the permiability higher will the ability to allow the magnetic field pass through it.

Answer

In electromagnetism, permeability is the measure of the ability of a material to support the formation of a magnetic field within itself. Hence, it is the degree of magnetization that a material obtains in response to an applied magnetic field.

Answer

Permeability is the property of any material by virtue which, it supports the formation of magnetic field inside it. It is represented by µ. In  SI units, permeability is measured in henneries per meter (H/m or H·m−1).  The permeability constant (µ0), also known as the magnetic constant or the permeability of free space, is a measure of the amount of resistance encountered when forming a magnetic field in a classical  Vacuum The magnetic constant has the exact (defined) value (µ0 = 4π × 10−7H·m−1 ≈ 1.2566370614…×10−6 H·m−1 or N·A−2).
