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

1. The problem statement, all variables and given/known data

THe problem is number 3 in the picture.

2. Relevant equations

3. The attempt at a solution

Lens law changing magnetic flux through the loop not sure which way for each one little confused. Thank you

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.
