Why no induced current when these coils are stationary?

Click For Summary
SUMMARY

Induced current does not occur between stationary coils because electromagnetic induction requires relative motion or a changing magnetic field. The discussion emphasizes that while there may be moving charges in one coil, without movement or a varying magnetic field, no current is induced in the adjacent coil. Understanding the principles of transformers, which operate on alternating current (AC) rather than direct current (DC), is crucial to grasping this concept. The forum encourages users to explore the relationship between magnetic fields and induced currents for deeper insights.

PREREQUISITES
  • Understanding of electromagnetic induction principles
  • Knowledge of transformer operation with AC and DC

These is there no induced current when the coils are stationary relative to each other? Isn't there still current (moving charges) in the the one on the left to cause a current in the one on the right when neither coil is moving?

this almost looks like homework/schoolwork ?
we will guide you, but we won't give direct answers

do you know why a transformer works with AC and not DC ?
if you do, then you know the answer to your above problem
if you don't, then go search google for the answer :smile:

think about the magnetic field and what it is doing, rather than the currentDave
