What is nature of curve obtained in Stewart and gee apparatus

Stevard and Gas Experiment
Learning objectives in orbit and classroom
out of class

The student must be able to see the video at the end of the video;

So determine the intensity of the magnetic field and depending on which factor (scale of scale)
How to describe the difference between the distance and tone of the angle of graph deflection
In class

Compare the theoretical and experimental magnetic field intensity (analyze the level)
Students will be able to evaluate the intensity of the magnetic field at different points with the axis of the circular trough carrying current
Students will be able to calculate the value of the intensity of the area for different values ​​of the present and the number of horoscope (make)
AIM:

To study the variation of the magnetic field with the distance on the axis of circular current by the method of Stewart and G

Tool: Connecting tangent galvanometer, resostat, switchboard, plug keys, storage cell, AMMeter (0-2 APP) and wires to Stewart and G.

Device Details:

The mechanism consists of a circular shape wooden frame on thick insulated wire wounds. Border horizontal support (weapon) has been fixed, which has been awarded a bachelor's degree in the semester, which has been fixed in the middle of the scale. Slide on horizontal support which has a stand to catch the deflection magnitometer. The height of the stand is such that the center of the magnetic needle passes through horizontal plane through the center of the horoscope.
