Finally, the switch on the electromagnet is reopened. Immediately after the switch is opened, which statements below are correct?

The magnitude of the flux through the loop decreased as the switch opened.

As seen from the left $($core$),$ the current induced in the loop is counter$-$clockwise.

The magnitude of the flux through the loop remained constant.

No current was induced in the in the loop.

As seen from the left $($core$),$ the current induced in the loop is clockwise.

The magnitude of the flux through the loop increased as the switch opened.
