I have been reading ahead in my course from Griffiths textbook and I have a couple of questions. I found this solution online to a question: http://glennrowe.net/physicspages/2013/09/23/balancing-magnetic-force-with-gravity/ It says: A square loop is cut out of a thick sheet of aluminum. It is...

At the moment we are working through problems in Griffiths' Electrodynamics textbook and it got me thinking... In magnetostatics we have the magnetic vector potential A and in the use of dielectrics problems we have the vector D. Why is it advantageous to use these vectors and not just stick to...

I see, so I will end up with a whole lot of new vectors for x, y, z, xhat, yhat and zhat. The I have to do is some algebra and make it look pretty? I think I got it now! I really appreciate your help, thank you so much :)

How do I do this? I'm not sure how to use those relationships since I've done very little with matrices.

So to transform the x,y and z I have to use And to transform the unit vectors I have to use Is this right?

I am in love with cylindrical coordinates :P No I joke, I just want to practice using them. I have seen those relationships before, in fact I went through the derivation, so I think I understand them. Where I'm confused is how to apply them to the E field formula. Since we have only r showing...

Hi everyone, I am new to the physics forums and I need your help :) I understand that depending on the symmetry of the problem, it may be easier to change the coordinate system you are using. My question is, how would I convert the electric field due to a point charge at the origin, from...
