An Innovative Device to Monitor Material Quality using Magnetic Permeability

Abstract

the proposed concept in this paper aims to design an instrument that measures and compares the magnetic permeability of the given substance, hence to determine the purity of the sample in a non-destructive manner. This works based on the stimulation method, where the magnetic field acts as a stimulator. A certified pure sample of milk is analyzed using this device to get the standard permeability of the milk. Then this sample is diluted with a known amount of water and the deviation of permeability is studied. The attained results are used to calibrate the device. The equation, which is modeled from the results, is used to interpret the purity of the given sample. The sample that has undergone the test procedure is safe to be reused. This is an effective Non-Destructive Test (NDT) to know the adulterant. Not only milk but other fluids such as hydraulic oil, fuels, and solids can also be tested for their impurity content. This device can also be used as a complementary for Electronic Tongue. It is a more efficient method where the comparative study of materials is used. Further, this method can be used to approximate the boiling and freezing point of the same when the exact composition of the material is known
