Forschungsarbeit aus dem Jahr 2013 im Fachbereich Physik - Experimentalphysik, Note: 1.0, University of Cambridge, Sprache: Englisch, The hysteresis of mild steel, transformer iron and a cupro-nickel alloy in an applied magnetic field were examined in order to establish the energy loss per cycle and the range of relative permeabilities of the materials. This was done by measuring the B-field produced by an applied H-field by inserting the material into two coils wound around each other. Current was passed through the primary coil producing a known H-field and by integrating the emf induced in the secondary coil, the B-field was measured. For mild steel, the enery loss per unit volume per cycle was found to be 43±2 kJ m-3 and 14.8±0.2 kJ m-3 for transformer iron. For the Cu/Ni alloy, a change in behaviour was observed as a function of temperature, because it has a Curie Temperature of 40°C. At 3.0±0.5°C, the energy loss was established as 800±40 J m-3. The ranges of the relative permeability were measured as 17.0±0.5 < ?r < 128±2 for mild steel and 26±2 < ?r < 246±3 for transformer iron. Subsequently, the relationship of energy loss with temperature for the alloy was examined and close to its Curie Temperature and was found to be exponential.

For the Cu/Ni alloy, a change in behaviour was observed as a function of temperature, because it has a Curie Temperature of 40C. At 3.00.5C, the energy loss was established as 80040 J m-3. The ranges of the relative permeability were measured as 17.00.5 r 1282 for mild steel and 262 r 2463 for transformer iron.
