**Lenz's and Faraday's Law Induction. Help on resistor and switches!**

## Homework Statement

Find the direction of the current in the resistor shown below a) at the instant the switch is closed b) after the switch has been closed for several minutes and c) at the instant the switch is opened

## Homework Equations

V = -N(flux/t)

flux = BA

## The Attempt at a Solution

Seriously, I have no idea how to start with this problem. ok, so let's look at (a) first. When switch is closed, the current is moving from the right side of the battery, through the loop and ends at the left side. Okay, and then at (b) after the switch has been closed for several minutes, what difference would it make? Maybe the value of V will decrease because of the above equation, V = flux/t? Okay, and at the instant the switch is opened, there would be no current? Somehow, I think the answer to this question is way too easy. Please check if I did anything wrong. Any help would be appreciated, thanks
