In
Lab 10 we experimented with magnetic fields, studying how they acted and where
they were directed between a magnets north and South Pole. During this
experiment we measured our first 3 dimensional object that was large enough to
interact with, a Helmholtz coil.
We
were tasked with measuring it’s magnetic field lines to find where they went
and isolate its north and south poles. to do this we took a compass and a sheet
of paper to track the needles direction and began moving the compass in differing
areas of the coil, marking the needles facing on the sheet of paper every
roughly 30 degrees. Doing this we noticed that the field seems to move as shown
below.
This showed us the main movement and area of the coils magnetic
fields, and how similar they could be. The coil has a single moving line going
through its center as a result of the cancelling effects of the different
fields on either side of the center, creating a uniform and regular magnetic
field that can be easily modified.
Possible flaws
due to our only
measuring every 30 degrees we could have possibility missed or failed to gain
the fields size due to measurement or user error, additionally as we could not
directly trace it very well on the sheet of paper we were unable to guarantee
that it was correct, a better way to possibly perform this experiment in the
future would be with metallic dust that we could track and monitor to see how
it moved in relation with the magnetic fields, but that could end up being too
much of a mess to clean up to be worth using.
