How to Calculate and Solve for Apparent Conductivity | Electromagnetic Method

The image above represents apparent conductivity.

To compute for apparent conductivity, five essential parameters are needed and these parameters are Angular Velocity (ω), Magnetic Permeability (μo), Coil Spacing (S), Amplitude of Secondary Field (Hsand Amplitude of Primary Field (Hp).

The formula for calculating apparent conductivity:

σ = 4Hs / ωμoS²Hp

Where:

σ = Apparent Conductivity
ω = Angular Velocity
μo = Magnetic Permeability
S = Coil Spacing
Hs = Amplitude of Secondary Field
Hp = 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
μo = Magnetic Permeability = 12
S = Coil Spacing = 9
Hs = Amplitude of Secondary Field = 2
Hp = Amplitude of Primary Field = 4

σ = 4Hs / ωμoS²Hp
σ = 4(2) / 3(12)(9)²(4)
σ = 8 / 3(12)(81)(4)
σ = 8 / 11664
σ = 0.000685

Therefore, the apparent conductivity is 0.000685.
