Introduction to Gauss's Law(Update)

This was the second day that we went over eletromagnetics in call. I will talk about what happends in a eletromagnetic field, what happens inside a Faraday Cage, and the field that two eletrons create when they are near each other along with other more advance equations. We will create a more elabrate understanding of the little game that we played at the end of the last blog post.

Here we can see how a negatively charge electron travels when it goes through a Electronmagnetic field. Depending on how fast the electron is moving it will make it across the field or colid with the positive side. Here my group prediced that the electron was moving fast enough to make it across. Since the negative charge is attracted to the positive side it will curve downward after leaving the field.

Here we where asked to to show what we should do if we were in the middle of a lighting storm and was in a car. I personally thought we should have went outside with our embrallas course, and enjoy the sight. Its a once in a life time experience; however, my group thought it would be a better idea to stay inside the car. They said it was something about Gauss's Law and/or Faraday cages.

Well if fact they are right since if you are in the car the lighting will not go through the car. Well it will not shock anyone inside the car and instead will stay on the outside and be grounded to earth.

We are introduced to torsen (a.k.a torque) inside a Electromagnetic field between two point charges. It is a farily simple equations; as seen below.

This is the equations for torsen. All that is needed is the Force (F) that each electron is producing on each other, the distance (r) from each other, and the angle with respect to the x-axis. This is a simple  Physics 2A problem just with electrons.

Now this is something that i hope that is not on the test on Thursday since I am still very unfamilar with the processes need to achieve the right answer.

We are being introduced to a Faraday Cage. This is were we predicted what will happen to the two square strips of foil papers. We thought it was going to push the foil away from the cage in both directions but we were wrong.

This is what really happen. This picture is also drawn out below since it is quite blurry.

This was what my group picked the first time I was in the class.

This was the option that my grouped picked the second time.

Both options were identical though I did not put much input the second time because I wanted my group to have the same experience I had when i first do the exercise.

Faraday Cage

This is how a possitve and negative charge electron react to each other. They create a field all around they pulling and pushing electrons that get near they. This what was happening in the little game we did last lecture period.

This is a follow-up to the picture of the red and blue electrons. Here we see the field that hone electron makes by itself. Also we see the field that two electron makes when they are opposite from each other. We also see that there is no E if you make a circular path around both of the electrons. That means that there is a net change of zero. In the picture of only one electron there is a E of zero also since it is equaly defused. This is what we call Flux.

These were the answers of the questions for the little lab that we did on the computer. I understand the flux concept but I will need to practice the are formula because it will get really complicated later.
