The class began with Professor Mason holding a bar and a compass. Then he showed us that when the compass came into close contact with the compass it no longer pointed just north. He then asked us to get a magnet and put it on the board and put the compass around the magnet. Then he asked to draw the direction that the compass arrow pointed. The picture of what we got is shown below.
After finding out that the arrows in fact made a magnetic field which was made by the magnet we were to draw the lines of the magnetic field. The picture of what it looked like is shown below.
We then moved on to the topic regarding magnetic flux. Professor Mason gave us the relationship between magnetic field and area as well as the angle between those two vectors. We were also able to draw the direction of each of the components for Force, Magnetic field and voltage using the right hand rule.
Professor Mason also showed us how the directions of the fields we drew were applied to an actual wire.
Here is a video of how it was supposed to look like.
We later moved on to applying previous definitions in order to find the relationship between force, current, mass, velocity, frequency and current.
Lastly, we talked about the effect of a magnetic field on a circuit and found that the force was perpendicular to the current and we also observed how a spin on the magnetic filed would affect the current which is shown in the picture below.
Overall, we were introduced to magnetism and how a magnetic field would affect force and voltage and we also linked the concept of magnetism to previous concepts we had previously learned.
