Experiment 10 Magnetic Fields and Induction
... 2. Connect the solenoid to a DC power supply of 15 V. Divide this voltage by the total resistance of the solenoid and the resistor to obtain the current I through the solenoid. The resistance of the solenoid is also labeled on it. Now you have all the information for your theoretical calculations. 3 ...

... If we plot the net field BM as function of the applied field Bo we get the loop shown in the figure known as a "hysteresis" loop. If we start with a unmagnetized ferromagnetic material the curve follows the path from point a to point b, where the magnetization saturates. If we reduce Bo the curve fo ...
