How to Calculate and Solve for Apparent Conductivity | Electromagnetic Method

Last Updated on April 6, 2024

The image above represents apparent conductivity. To calculate apparent conductivity, five essential parameters are needed and these parameters are Angular Velocity (ω), Magnetic Permeability (μ_o), Coil Spacing (S), Amplitude of Secondary Field (H_s) and Amplitude of Primary Field (H_p).

The formula for calculating apparent conductivity:

σ = ^4H_s / _ωμoS²Hp

Where:

σ = Apparent Conductivity
ω = Angular Velocity
μ_o = Magnetic Permeability
S = Coil Spacing
H_s = Amplitude of Secondary Field
H_p = Amplitude of Primary Field

Let’s solve an example;
Find the apparent conductivity when the angular velocity is 3, the magnetic permeability is 12, the coil spacing is 9, the amplitude of secondary field is 2 and the amplitude of primary field is 4.

This implies that;

ω = Angular Velocity = 3
μ_o = Magnetic Permeability = 12
S = Coil Spacing = 9
H_s = Amplitude of Secondary Field = 2
H_p = Amplitude of Primary Field = 4

σ = ^4H_s / _ωμoS²Hp
σ = ⁴⁽²⁾ / _{3(12)(9)²(4)}
That is, σ = ⁸ / _3(12)(81)(4)
σ = ⁸ / ₁₁₆₆₄
σ = 0.000685

Therefore, the apparent conductivity is 0.000685.
