Investigate the strength of a magnetic field from a permanent magnet as a function of distance.
The strength of a magnetic field varies with distance from a magnet. The strength of a magnetic field could vary inversely as the square of the distance, similar to the strengths of gravitational and electric fields...
... or, the strength of a magnetic field could vary in a different way relative to distance. Unlike gravitational fields that are radial, a magnetic field consists of complete loops that surround and go through the magnet.
Materials and Equipment
Collect all of these materials before beginning the lab.
The steps to the left are part of the procedure for this lab activity. They are not in the right order. Determine the correct sequence of the steps, then take a snapshot of this page.
A.Place a magnet next to the 5 cm mark on the meter stick with the north pole of the magnet facing the sensor.
B.Place the magnetic field sensor so the end of the rod is even with the zero end of the meter stick.
C.Proceed to data recording and manual sampling for every 1 cm increase in the magnet's position up to 15 cm.
D.Place a meter stick on a flat surface.
Q1: Why do you think it is important to have the tip of the magnetic field sensor pointed at the middle of the magnet, rather than off axis?
This number should match the actual distance between your magnet and the sensor.
Note:If your magnetic field measurements are negative, turn the magnet around such that the North end is pointing towards the sensor.
Q2: The magnetic field sensor measures the axialfield strength component from the magnet. What do you think the magnitude of the radial (perpendicular) field strength component would be without actually measuring it?
