Abstract: This thesis provides insight into the magnetic phenomenon of Hysteresis.Hysteresis is defined as a retardation effect where the magnetization of a magnetic material lags behind the magnetizing force.Here we will explore the hysteresis loop for a silver steel ferromagnet and use this to discover its magnetic properties.The method used will be to place a ferromagnet inside a solenoid with an alternating voltage which will continually reverse the magnetic field and magnetism direction.The relation between these two quantities will be used to produce a hysteresis loop from which magnetic properties can be deduced.The results obtained were: saturation magnetization = (8.4±0.5)(10 5 )Am -1 ; remnant magnetization = (5.9±0.5)(105)Am-1 ; coercive field: (4.3±0.5)(10 4 )Am -1 ; energy expended per cycle per unit volume of material: (1.55±0.05)(10 3 )Jm -3 s -1 ; energy product: (8.7 ± 3.0)(104)Jm -3 .
