Stewart and Gee’s Method
Determination of Magnetic Field along the Axis of a Current-Carrying Circular Coil
1Q. What is the magnetic induction formula at a point x, away from the center of the circular coil?
2Q. What will be the Magnetic field value at the center of a current-carrying coil?
3Q. Does earth’s horizontal magnetic field value remain the same everywhere or it fluctuates?
4Q.What are the two factors to calculate the earth’s horizontal magnetic field value online (https://www.ngdc.noaa.gov/geomag-web/#igrfwmm)
5Q. The angle which you measure by the Deflection Magnetometer is with reference to the earth’s magnetic field component or the magnetic field produced by current-carrying coil?
6Q. Why do you put apparatus (Wooden Frame along with circular coil) in East-West Direction?
7Q. What is commutator and what its role in an experiment?
8Q. What is the difference between the Helmholtz coil and Solenoidal?
9Q. What is the relation between Gauss and Tesla?
10Q. What is the unit of magnetic field intensity H?
11Q. When you plot the graph in-between the tan-theta and distance, you observe Gaussian type shape of the curve. On this curve, you find the points of inflection what is the formula for that?
12Q. The magnetic field of induction increases one side of the center and decreases on other sides. Can we create a uniform magnetic field with the help of this concept?
13Q. How many turns (50, 100, 500, 1000, etc) you have used in your experiments in the current-carrying coil?
14Q. Can you perform the experiment by using the Alternating Current?
15Q. Do you feel any application of this experiment?
