Question

what is the value of u°/4π​

Answer 1

Answer:

value of  u°/4π = 4π × 10−7 H/m ≈ 12.57×10−7 H/m.

Answer 2

Given

• u°/4π

To find

• To find the value of the given constant

Solution

we are provided with the constants which comes in the biot-sartvat law and are asked to find the value of the constant.

we know that Biot savart law explain and estimates the magnitude of magnetic field which is experienced at a point due to the presence of a current carrying conductor.

The relationship between magnetic field and the current carrying wire is elaborated in the law, jointly contributed from the experiments of 2 scientist Baptiste Biot and Felix Savart.

In the Biot savart law, u° he is known as permeability of the free space and has a value of

4π × 10^(-7) Tm/A

Therefore, u°/4π = {4π × 10^(-7)}/{4π}

or, u°/4π = 10^(-7)
