1) This figure represents the hysteresis curve of a Magnetic material.
2) a) Virginal Curve ( Dotted Line) : It is the magnetization curve of a freshly prepared magnetic material.
b) Coersive Force (Hc) : It is the value of magnetic field that needs to be applied to make flux density (B) zero.
c) Maximum flux density ( Bmax ) : It is the maximum value of flux density that can be made inside the magnetic material by increasing Magnetic field.After point P we can't increase flux density beyond ( Bmax)
d) Residual Magnetism ( Br ) : In the demagnetization process though we made H equal to zero but B won't be zero because of Hysteresis property of Magnetic materials.

Question 1. What does the slope of the plot of tension
force vs. position represent?
Question 2. For the second run, do you notice nonlinear
behavior at high tension forces? Does this indicate the material is
becoming stiffer or slinkier?
Question 3. What does the trend in the graph indicate
will happen if you keep adding even more tension to the
wire?

Q.3 What does figure 5 and figure 6 represent in page 10 in your laboratory manual? 10 The power source is usually a couple of terminals on the lab table. G represents the galvan The/VVV symbols stand for the resistors in the voltage divider. If there are actually 10 resistors of equal magnitude on your terminal board, as shown in Figure 4, then the voltage across each resistor will be 1/10 of the power supply voltage. You can measure the...

1. Let x represent the dollar amount spent on supermarket impulse buying in a 10-minute (unplanned) shopping interval. Based on a certain article, the mean of the x distribution is about $24 and the estimated standard deviation is about $7. Is it necessary to make any assumption about the x distribution? Explain your answer. a. It is not necessary to make any assumption about the x distribution because μ is large. b. It is necessary to assume that x has...
