Experimental Procedures Materials and Methods Animals and housing In this experiment, eighty female albino rats, weight between 190±10gr took part in 20 selective groups (subgroups).
Calibration of material types on the intensity of SMF Impacts of different materials (cartoon, PVC, wood, plastic, iron, glass, and Mild steel) on the intensity of a uniform static magnetic field (SMF) proved through designing a multi Helmholtz coil connected in series.
The results showed that the materials of a cartoon, PVC, wood, plastic, and glass have no significant impacts on the exposed magnetic field (lossless of SMF).

In order to manufacture hypoid gear qualified on the machine, the need for multiple cut and try to adjust the processing parameters, this process leads to the waste of human and material resources, but also can not adapt to current market requirements for product development.
With the development of science and technology, the hypoid gear set higher requirements, high speed, heavy load, low noise and high reliability that become the future direction of development.
