Hi, I'm new to this site. Anyway, I am studying for the MCAT right now and the physical science review that I have been doing has gone pretty well, I just have a few questions about comparisons that can be made between movement of electrons and movement of solid objects.
1) What is the...
1. Is Ampère's law (\nabla \times \mathbf{B} = \mu _0 \mathbf{J}) consistent with the general rule that divergence-of-curl is always zero? Show that Ampère's law cannot be valid, in general, outside magnetostatics. Is there any such "defect" in the other three Maxwell equations?
I'm not...
I'm having trouble starting this problem... I'm pretty sure I'll be able to figure it out if I can just get past the first question.
I scanned the sheet because I'm lazy and I thought that you'd be able to understand the problem better that way anyways.
So if someone could just point me in...
Hi my grade 11 physics class is on its final unit (Electricity and Magnetism) and I am a little lost... So far we are doing Charge and Voltage (we learned the formulas)... and we're expected to know that circuit diagram stuff and Ohm's Law? lol a bunch of stuff we were suppose to learn in grade...
Hello,
I was wondering if you guys know any websites/ free books/ any other ressource about physics electricity and magnetism, since this is my next class and I want to try to read about it before starting. I have download an e-book from the sticky, but I'd like other sources.
feel free to...
I have a huge problem to work out..
but first, i can't find the equations for
(1) electrostatic potential of the center of a square (a charged particle at each vertice)
and
(2) the magnitude of electric field at the center of the same square.
These are both questions to two...
help! questions on electricity and magnetism
1. What is the frequency of the magnetic filed if it is know to be perpendicular to the electric field. The magnetic field is 0.00178T and the electric field is 8000V/m.
2. I just need the angle for this one. At a certain location, the...
ive been doing some thinking to a question brought up by my advanced physics teacher...i can't really back up any of my responses though...any help on whether electricity and magnetism are more alike or different?
Not even sure where to begin with this question:
Estimate the magnitude of the potential difference produced by the motion of a conductor in the Earth's magnetic field for which B is 4.3x10^-5T and the angle of dip (the angle it makes with the horizontal) is 60 degrees. Take as an example a...
I just finished a Physics course in Electricity and Magnetism and never worked so hard for a 'B' in a class. I'd really like to go over the material once more to get a better handle on it during our break. I was thinking that a fresh approach with a different text might help, so I was hoping I...
