This question has been bugging me. I saw it in a few GCE past papers.
You know that diagram for Lenz's Law in all textbooks ? It shows a magnet entering a solenoid....
okay, How do I predict which way the Galvananometer or ammeter will defelct ? Like will go tot the right or left and why ?
Like in the diagram below :
Which way does the ammeter pointer deflect towards ? Left or right ?
