Lab 10 - Magnetic Field of a Coil
PRELAB QUESTIONS
1. What is a solenoid?
2. What quantities will you be graphing in this lab?
3. The equation for the magnetic field of a solenoid given in your book, B = μ0nI, is oversimplified. What assumption is made and how is this different than what you have in lab?
the question does not need any extra information
if you do not know the answer do not put any comment
Homework Answers
1. A coil with many circular close turns of insulated copper wire is a solenoid. One end of such a solenoid behaves like the north pole and the other as a south pole. Therefore magnetic field due to current in the solenoid is similar to a bar magnet.
2. Magnetic field intensity v/s position at the axis of solenoid.
3. Assumption .
i) Magnetic field outside is zero.
ii) Magnetic field inside the magnet is uniform, both in direction and magnitude.
iii) Length of solenoid is very large.
In Lab, Length is finite and small, Magnetic field inside is not uniform and outside it is not zero.

Short answer for magnetic permability and ferromagnetism lab. Fe
cubes were stuck into a solenoid, and there were changes to the
permeability relating to when there were one, two or three cubes
present.
1) What is the effect of changing the number of Fe cubes in the
solenoid? Why do you suppose this change occurs?
2) What is the effect of changing the sample material? Compare
your results using book values for permeability of Fe and Cr. Do
the results...

Pre-Lab for Experiment 03 A: A magnetic field in a solenoid is parallel to the axis of the solenoid. The current along the end of the teeter-totter is perpendicular to the magnetic field and therefore produced a force of F = 1, L,B, where 1, is the current in the teeter-totter and L, is the length of the conductor at the end of the teeter-totter. When well balance, weights on the other end of the teeter-totter produce a downward force...

In Lab 11 you simulated how a magnetic field can be produced by a conducting coil when powered by a DC and an AC generators. You explored the differences between the resulting magnetic fields. Consider an experimental set-up identical to what you used in the lab: a large coil connected to an AC power supply. Assume that the maximum voltage supplied by the generator stays the same but the frequency of the supplied voltage changes. As frequency changes, you measure...

1. Consider a solenoid, such as the slinky used in part B of the experiment. What would happen to the magnetic field inside this solenoid if you doubled the number of turns while simultaneously stretching the solenoid to twice the original length? Assume the voltage applied was kept constant and the additional length of wire for the extra turns of the coil do not add appreciably to the resistance of the solenoid. Which would be the result? a) The magnetic...

The following questions refer to a coil of radius 10.5 cm with 100 turns. 1) What is the expected slope for the plot of magnetic field vs. current? (Refer to Equation 1 if you’re not sure how to answer this.) 2) A student performs the lab and measures a slope of 6.3 x 10-4 T/A. Based on this result, what value do they calculate for μ0? What is the percent error between their value and the theoretical value? 3) What...
