  core loss
-It is well known that electrical logs of boreholes can play a signi|fi|cant role in base metal exploration in identifying mineralised zones, especially when there is core loss or the borehole diameter is small or if drilling is by percussion.
      
The core loss increased by the eddy current loss through the laminations was 78% of all deterioration by interlocking.
      
Magnetic deteriorations by interlocking was caused by the core loss increased by the obstruction of magnetic flux flows and eddy current loss through the laminations.
      
Core loss of the test specimens declined for zirconium contents of 0.01 wt.%, whereas the magnetic induction did not change due to the addition of zirconium less than 0.133 wt.%.

Magnetio parameters of equivalent fundamental frequency, such ascomplex permeability μ, inductance permeability μ_L, magnetic dissipation factorD_m and quality factor Q, as well as the total core loss P_c can be measured by theautomatic bridge technique. In bridge circuit, the priniple of vector impedance ra- tio measuremeut is applied. Fundamental frequency character is obtained by multi-plication device to overcome the difficulty due to the non-linearity in A. C. magneticmeasurement. Dual-slope A/D conversion method is used for measuring variousratios. With some other auxiliary circuits, parameters of hysteresis loop, such asmaximum induction B_m, magnetizing force H_m, peak permeability μ_p, residual inductionB_T, coercive force H_c and squareness ratio B_T/B_m can be also measured in a singleinstrument. All digital results of measured parameters are displayed or printed inmagnetic unit system for direct reading. Accuracy of measurement is ±1~3%.Working frequency is from 50Hz to 5kHz. Measuring function and range change arecontrolled by logic circuit. This design automatizes the measurement of all A. C. mag-netic properties and results in convenience of designing an automatic measurementsystem for magnetic parameters by microprocessor.
