Sir,
When a current is passed through a conductor, a magnetic field is produced around it. Due to the flowing charges, is an electric field also produced around the conductor?
 
Physics news on Phys.org
You might have to think just about when, how and where is and electric field is formed. Has magnetic effect of current flowing through a conductor anf those forces started for you. Then you must understand the following. Probably you read H C Verma or Resnick Halliday for better understanding. You can even refer to the NTSC CBSE 11-12th textbooks. The explanation is in simple english there.
 
yes there is also an electric field. that's why power lines humm because of the huge potential they have relative to the air and the effect it has on the moisture
 
Thread 'Need help understanding this figure on energy levels'
This figure is from "Introduction to Quantum Mechanics" by Griffiths (3rd edition). It is available to download. It is from page 142. I am hoping the usual people on this site will give me a hand understanding what is going on in the figure. After the equation (4.50) it says "It is customary to introduce the principal quantum number, ##n##, which simply orders the allowed energies, starting with 1 for the ground state. (see the figure)" I still don't understand the figure :( Here is...
Thread 'Understanding how to "tack on" the time wiggle factor'
The last problem I posted on QM made it into advanced homework help, that is why I am putting it here. I am sorry for any hassle imposed on the moderators by myself. Part (a) is quite easy. We get $$\sigma_1 = 2\lambda, \mathbf{v}_1 = \begin{pmatrix} 0 \\ 0 \\ 1 \end{pmatrix} \sigma_2 = \lambda, \mathbf{v}_2 = \begin{pmatrix} 1/\sqrt{2} \\ 1/\sqrt{2} \\ 0 \end{pmatrix} \sigma_3 = -\lambda, \mathbf{v}_3 = \begin{pmatrix} 1/\sqrt{2} \\ -1/\sqrt{2} \\ 0 \end{pmatrix} $$ There are two ways...
