A long piece of wire with a mass of 0.1kg and a total length of 4m is used to make a square coil with a side of 0.1m. The coil is hinged along a horizontal side, carries a 3.4A current, and is placed in a vertical magnetic field with a magnitude of 0.01T.
a) Determine the angle that the plane...
The magnetic vector potential is given as:
\mathbf{A}(\mathbf{r}) = \frac{\mu _0}{4\pi }\int \frac{\mathbf{J}(\mathbf{r'})}{|\mathbf{r} - \mathbf{r'}|}\d\tau '
I am asked to show that \mathbf{\nabla } \cdot \mathbf{A} = 0 by applying the divergence to the equation above. When I've done...
Hello! I would SOOO appreciate any help I could get with this homework of mine!
I just don't understand and my phys instructor is mean!
Anyway, it's Phys 110, so it should be pretty easy for some of you, but it's hard for me...
Any help would be GREATLY appreciated!
You can IM me...
Questions garanteed to have you doing right handed impressions of rap artists by the end! :smile: :-p
Now I am much happier with electronics, I decided to start reading about magnetics. However, I'd appreciate any help you could provide with a few things I'm thinking about.
First of all...
Hi, I had a thought in my head and was just wondering something.
If I have 2 exact steel balls with the same inital velocity shooting staight up but will one of the balls there is a magnet just above a point where the velocity of that ball will be 0. The steel ball does not come into contact...
Hypothetical experiment:
I have a single 2-inch by 2-inch by 1-inch thick Neodymium magnet affixed on the outer rim of a 1-foot diameter circular hard plastic disk(1/8th-inch). The disk and magnet are held stationary by whatever means.
The underside of the plastic disk has a coating, an...
