A current of 2 A passes through a coil of 350 turn wound on a ring of ...
Solution:
Given data:
Current, I = 2 A
Number of turns, N = 350
Mean diameter, D = 12 cm
Flux density, B = 1.4 Wb/m²
Step 1: Calculate the magnetic field intensity (H)
Magnetic field intensity is given by:
H = (I × N) / (π × D)
Substituting the given values, we get:
H = (2 × 350) / (π × 0.12)
H = 1488.7 A/m
Step 2: Calculate the magnetic permeability (μ)
Magnetic permeability is given by:
μ = B / H
Substituting the given values, we get:
μ = 1.4 / 1488.7
μ = 9.4 × 10^-4 H/m
Step 3: Calculate the relative permeability (μr)
Relative permeability is given by:
μr = μ / μ0
Where μ0 is the permeability of free space, which is 4π × 10^-7 H/m
Substituting the values, we get:
μr = (9.4 × 10^-4) / (4π × 10^-7)
μr = 749.6
Therefore, the value of relative permeability of iron is 749.6 (approximately).
