Question

A group of students measured the interaction force between a wire in a magnetic field and the magnet responsible for the field using a wire of length 4.0 cm. They obtained the following results.

Not sure what I am doing wrong when making the graph on excel.

A group of students performed the same "Force on a Wire" experiment that you did in class. They obtained the following results Current (mA) Length (cm) Force (N) 895 882 904 901 4.0 3.1 1.9 1.0 0.0311 0.0233 0.0155 0.0078 (a) Analyze the data. (You will not submit this spreadsheet. However, the results will be needed later in this problem.) (i) Enter the above data into an Excel spreadsheet. (i) Make a plot of force versus length (ii) Use the trendline option in Excel to fit the data of force versus length to get the slope HINT HINT (b) Report this value below slope = .738 N/m (c) Now, use the average current to determine the strength of the magnetic field B in which the experiment was carried out Additional Materials Force on a Wire Appendix

Explanation / Answer

In the question it was said that the length of the wire used for this experiment is 4.0 cm. Then how come the length got decreased in each steps. The length of the wire was supposed to be a constant quantity. And accordingly the current and force would have adjusted.

Magnetic force on a wire is given by

F = A (current) * L (length) * B (magnetic field).
