Profissonal development and communication skills in english - Coursework ExampleIn this formula b is the top induction, f is magnetsing frequency, A is the cross sectional area of the sample and n is the number of turns of the search coil around this sample. In order to evaluate the curie temperature, a sample of the sheet metal is placed in an insulated temperature controlled furnace, which is then heated above its curie point. The sample is then let chill out victimization a low frequency 10hz magnetic field. Curie temperature is established by measuring magnetic induction and induction-temperature.The experiment was conducted using the following materials a furnace tube, a solenoid tube, a secondary tube, twain identical search coils and a sample sheet. The arrangement of above materials is illustrated in Figure 1. The search coils were wound around a smaller tube, which was inserted inside another longer and larger tube in a way that the axes of both tubes aligned together. The solenoid was wound around the larger tube. The stainless construction was then inserted inside the furnace tube.The furnace was heated approximately to 840 C because of it, the solenoid and the search coil also got heated to the same temperature. The steel sample was then inserted into star of the two search coils as shown in the figure 1. After a period, the sample, solenoid and the furnace reached the same temperature. The furnace was switched off, and the solenoid was switched on once the entire system reached the temperature equilibrium. The sample was then allowed to cool unforced.The experiment used 30 x 28 mm steel samples of various thickness cross-sectional areas of the samples are shown in the attached table. The use of two identical search coils in series connection eliminated air flux induction, thus ensuring that the induced EMF was causedby the sample magnetisation alone from an same magnetic field produced by the solenoid. The solenoid used a sinusoidal time varyi ng magnetic field the strength of it
