Test #3 question
** **
** **
My question is about one of the questions on test #3. . . Derive the expression for the voltage, as a function of clock time, induced in a coil of radius a as it rotates with constant angular frequency `omega about a central axis in the plane of the loop, with the axis perpendicular to a magnetic field B.
I know that angular freq= 2pi/T but I'm not sure how to connect this to the voltage produced by the rotating of the coil in clock time T. Do I need to use V= 1/(4pi*E)*(q/r)? Thanks
@& The angular frequency is correct and will be useful.
This is a case of voltage being produced by a magnetic field.
This problem is lifted directly from the Introductory Problem Sets. Be sure you completely understand those problems and their solutions.
The voltage produced is the rate of change of the magnetic flux.
No external electric field is mentioned here, to there's nothing to substitute for E. The formula you quote is not relevant to this situation.
Check out the intro problem sets then if you still have questions, let me know.
