Magnetism

Here we put a compass around a magnet to view the magnetic field around one
.

To see more clearly, we saw a picture of iron fillings sprinkled around a magnet.



Here we picked three surfaces, the big one around the whole magnet, one just to the left of the top, and one at the bottom. We found the net flux = 0, which proved the fact that a magnet can not have a single pole.


Professor Mason demonstrated the Lorentz Force with a magnet and an oscilloscope. When he approached the screen the parallel, nothing happened, but it did when it was perpendicular.



Here we sent current through a wire over a magnet. It repelled and attracted, depending on the current flow. This shows that current produces a magnetic field




Here we calculated the magnetic force of a bent wire. Instead of integrating, we just used excel.
