Hi, I have a question about a magnetic field.
there are 2 inductors
1. a magnetic field is created by a inductor
2. that inductor is shut off
3. The tricky part. I know that magnetic field collapses and causes a back-emf on the inductor but will the field that spread out still induce a voltage on another inductor even after the first one is completly off. say the 2nd inductor is far away but extremly sensitive. if not then why. the information that the inductor is off would not have had time to reach the furthest point yet?
this is a hypothetical question's
but if there is any math that could help then please please post it.
