An Investigation of Eddy Current, Solid Loss, Induced Voltage and Magnetic Torque in Highly Pure Thin Conductors, Using Finite Element Method

In this paper, eddy current, induced voltage, solid loss and magnetic torque in circular thin conductors were systematically investigated using finite element method. Two-dimensional models were constructed using ANSYS MAXWELL to simulate the magnetic field and current in a transient environment. A rectangular permanent magnet made of alnico5 was used as the rotational magnet. Simulations were carried out for four highly pure conductor metals, silver, bronze, tungsten and graphite. The electrical resistance of the specimens was calculated. The results of the simulations for these specimens show that there is a strong correlation between bulk conductivity of the specimens and eddy current induced in the thin conductor metals. The model presented in this paper can be used in measuring the electrical resistivity of the samples and non-destructive test studies of thin conductor thin films.
