What is the direction of the induced current in the loop for each situation?

Click For Summary
SUMMARY

The discussion focuses on determining the direction of the induced current in a loop based on changing magnetic flux, specifically using Lenz's Law. The participants analyze various situations, identifying the magnetic field direction threading the loop in each case. In situation 4, the magnetic field is confirmed to be directed into the page. Establishing the initial magnetic flux direction is crucial for accurately predicting the induced current's direction in all scenarios presented.

Clearly in situation 4, the field threading the loop is into the page - as signified by the crosses.

First step would be to establish the direction of the flux threading the loops in the other 4 examples. - ie into the page or out of the page.

Once you have established the direction of the flux to start with, we can analyse how that flux is changing; and thus the direction of the induced current.

SO get back with those initial B directions.

I see the examples as
1. top left
2. top right
3. lower left
4. lower centre
5 lower right

Just so we know we are referring to the same example each time.
