Question

Chap 22 Faraday's Law Concept Test Reference in the textbook: Chapter 23 The power supply is slowly turned un increasing the current in the scene Whle the current is increasing what is the direction of-d /dt Inside the solenoid? 1) -d/dt 0 2) To the right 3) To the left

Answer 1

Current is increasing througth power supply, Sua emf will induced in the solenoid and then induced current starts flowing .. This induced current will flow opposite to current through power supply by Lenz law. son cument from power flowing to the right Induced current will flow to the left
