Question
oo T-Mobile LTE 5:34 PM capa8.phy.ohio.edu In Figure A, a loop of wire is laying flat in the plane of the screen in a magnetic field as shown. In Figure B, a loop of wire is laying flat in the plane of the screen to the side of an infinitely long wire. In each situation, decide whether or not there is an induced emf in the appropriate loop during the action described. 'emf means there was a non-zero induced emf. 'No emf means there was no induced emf in the coil Fig A Wire Fig B In Figure B the current in the wire starts at emf zero and is increased until 5A of current flows towards the right of the page while the loop is held stationary. emIn Figure B the current through the wire is kept constant at 3A to the right while the loop is moved towards the bottom of the screen towards the wire emf In Figure B the current through the wire is kept constant at 3A to the right while the loop is moved to the right parallel to the wire right side of the page bottom of the page The loop in Figure A is moved towards the The loop in Figure A is moved towards the Submit AnswerIncorrect.

Whenever magnetic field via loop is not parallel to plane of loop and it is not changing with time emf will induce.
Or if flux via loop is changing with time emf will induce
In A.emf will induce
In B. Emf will induce
In C.no Emf will induce (since parallel to wire flux is not changing
In D.No emf will induce (until loop completely lies in the field region)
In E. No emf will induce
