# How to Calculate and Solve for Shielding Factor | Polymer & Textile The image above represents shielding factor.

To compute for shielding factor, two essential parameter are needed and these parameters are coil radius (Rs) and shielding depth (L).

The formula for calculating the shielding factor:

ε = Rs / L

Where:

ε = Shielding Factor
L = Shielding Depth

Let’s solve an example;
Find the shielding factor when the coil radius is 11 and the shielding depth is 21.

This implies that;

Rs = Coil Radius = 11
L = Shielding Depth = 21

ε = Rs / L
ε = 11 / 21
ε = 0.52

Therefore, the shielding factor is 0.52.

Calculating for the Coil Radius when the Shielding Factor and the Shielding Depth is Given.

Rs = ε x L

Where;

ε = Shielding Factor
L = Shielding Depth

Let’s solve an example;
Given that the shielding factor is 30 and the shielding depth is 5. Find the coil radius?

This implies that;

ε = Shielding Factor = 30
L = Shielding Depth = 5

Rs = ε x L
Rs = 30 x 5
Rs = 150

Therefore, the coil radius is 150.

Calculating for the Shielding Depth when the Shielding Factor and the Coil Radius is Given.

L = Rs / ε

Where;

L = Shielding Depth
ε = Shielding Factor

Let’s solve an example;
With a shielding factor of 24 and a coil radius of 14. Find the value of the shielding depth?

This implies that;

ε = Shielding Factor = 24
Rs = Coil Radius = 14

L = Rs / ε
L = 14 / 24
L = 0.58

Therefore, the shielding depth is 0.58.
