Point charge induced current on a conducting ring

AI Thread Summary
A conducting copper ring experiences induced current when point charges pass through its center. The key equation relating charge Q to the induced current involves Faraday's law of electromagnetic induction. To measure the induced current effectively, contacts should ideally be placed at the outer radius of the ring for optimal readings. One contact connects to an electrometer, while the other should be grounded to complete the circuit. The discussion emphasizes the expectation of a current induced to flow around the ring due to the movement of the point charges.

Hello,
I have a conducting copper ring of inner radius a and outer radius b.
point charges Q pass through the centre of this ring for time dt.
so I guess I'm suppose to get a step function of induced current or something similar.

1)what is the equation relating the charge Q to the induced current on the ring?
2)where should I place the contacts to measure the induced current (inner radius / middle/ outer radius of the ring)?
3)one of the contacts is placed on the ring and goes to the electro-meter, where does the other contact go to get an electrical circuit? grounded?
thank you,

Do you imagine that a current is induced to flow around the ring, or what?
 

Thread 'How to picture the vector potential?'

Susskind (in The Theoretical Minimum, volume 1, pages 203-205) writes the Lagrangian for the magnetic field as ##L=\frac m 2(\dot x^2+\dot y^2 + \dot z^2)+ \frac e c (\dot x A_x +\dot y A_y +\dot z A_z)## and then calculates ##\dot p_x =ma_x + \frac e c \frac d {dt} A_x=ma_x + \frac e c(\frac {\partial A_x} {\partial x}\dot x + \frac {\partial A_x} {\partial y}\dot y + \frac {\partial A_x} {\partial z}\dot z)##. I have problems with the last step. I might have written ##\frac {dA_x} {dt}...

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (Second part)'

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. In the page 196, in the first paragraph, the author argues as follows ...
