A ring is rotating through a constant magnetic field. Indicate whether there is induced current in the transitions between each of the states of the ring.

State $1$ to State $2$: ring is horizontal in a vertical magnetic field and rotates to an angle of $=45$$=45.$

Yes, there is an induced current going counter$-$clockwise around the ring when viewed from above.

No$,$ there is no induced current.

Yes, there is an induced current going clockwise around the ring when viewed from above.

There's not enough information to tell.

State $2$ to State $3$: Ring is at an angle of $=45$$=45$ in a vertical magnetic field and rotates to be vertical.

Yes, there is an induced current going clockwise around the ring when viewed from above.

Instead, consider the case when the ring is rotated in the opposite direction. For the case of moving from State $3$ to State $2,$ what would be the effect on the current in the ring?

State $3$ to State $2$: Ring is vertical in a vertical magnetic field and rotates to an angle of $=45$$=45.$

Yes, there is an induced current going counter$-$clockwise around the ring when viewed from above.
