Hi All,
Please take a very long tightly wound solenoid of any radius with another coil wound around the outside of it. Now, if a current is applied to the solenoid, the changing flux of the magnetic field causes an induced emf in the outside coil which is perfectly consistent with the math of the situation.
Although the math is perfectly obvious to me, I don't understand how such a thing could happen. The wire in which the emf is generated is in a part of space where absolutely nothing happens. Put the whole set up in a vacuum and the wire is then in a part of space where there is absolutely nothing!
How could such a thing happen?
Thank you,
Bob
