![Lab Report: Magnetic field of the electric current passing in a solenoid
Data and data analysis:
I(mA)
B(mT)
0.2 mT
O.3 mT
0.4mT
O.5mT
2.76 mA
4.62 mA
1o.46MA
16.79MA
2 3.8mA

• Equipment:
Variable resistor, solenoid, Gauss meter, DC voltage, Ammeter and connecting wires
Design an electrical circuit to test the hypothesis
Experimental Procedure:
1. Connect the circuit.
2. Connect the ammeter in series with DC voltage.
3. Vary the current I passing the solenoid by varying the resistance of the resistor.
4. Measure the magnetic field B corresponding to each value of the measured current I in table
(1).
5. Make a graph between B(mT) in y-axis and I(mA).
6. Determine the slope of your best fit line with error.
7. Using your value for the number of coils per unit length of the solenoid and the slope calculate
an experimental value for the permeability of free space Ho

Transcribed Image Text:Discussion & Analysis of results:
7- Discuss your measurements of the magnetic field of the solenoid as a function of current.
Did these data agree with the theory?
2-Find the slope of the graph B(mT) versus I(mA)
...
X-Using your value for the number of coils per unit length of the solenoid and the slope
calculate an experimental value for the permeability of free space Ho
Compare your measured value for the permeability of free space to the theoretical value of
47TX10-7 T.m/A by computing a percent discrepancy.
...
5 - Does the relationship B versus I change when the number of coils per unit length of the
solenoid change?
6 - What happens when you change the material type of the coil into nickel and you set the
number of coils .
7- Calculate the experimental error for the following measurements: current and voltage
values.
Gauss matere n.Y X Ocb=
Ammeter-. X .
