Question #67125

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?

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?

2) What voltage would you expect to be able to induce in the coil by using a magnet that has a field

of B = 0.3 mT, if you quickly move the magnet into the coil in t = 0.05 seconds?
