Induction Rules

AI Thread Summary

Mutual induction in transformers occurs only when the voltage is switched on or off, as steady DC does not produce a changing magnetic field. Faraday's Law is applicable for analyzing the induced voltage in the receiving coil, while Ampere's Law can be used to examine the magnetic field generated by the sending coil. The discussion emphasizes that there is no positive feedback or infinite induction between the coils when DC is applied continuously. Understanding these principles is crucial for analyzing transformer behavior under different voltage conditions. The conversation highlights the importance of these laws in explaining mutual induction dynamics.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
