3Q: What is B and H, and what are the units in CGS/SI system?

4Q: What is Intensity of Magnetization?

5Q: What is susceptibility?

6Q: What is the unit of magnetic susceptibility?

7Q: What are the main differences between Diamagnetc, Pramagnetic and Ferromagnetic materials?

8Q: Why the meniscus level rise up or fall down in the presence or absence of external uniform magnetic


9Q: In which unit system (SI or CGS) you measured the magnetic field strength H?

10Q: In which unit you measured the fall in height of the meniscus ?

11Q: What is the formula to calculate the mass susceptibility of FeCl3 solution?

12Q: You have calculated the mass susceptibility for different values of current i.e. means different strength

of the external magnetic field H. You should take average of the susceptibility or have to plot graph
