Unformatted text preview: m) Graph 3. Graph of field strength vs distance in the direction of p. From here we can see clearly that as the radial distance increases, the field strength decreases non- linearly. The direction of the field lines is vertical, going down if north pole is on top and going up if south pole is on top. Hence the probe should be placed horizontally to cut the field lines. In either cases field gets weaker as we move away in the p direction. Force Between Magnets A piece of permanent magnet is placed on a digital scale and its weight is nulled. Then, another identical second magnet is fixed on a linear track and the distance between the two magnets can be adjusted. The two magnets repel each other and the force between them is measured in propor...
