Question
(a) Direction of the Current through the loopbeforet= 0 s ---Select---clockwisecounterclockwisethere is no current at this time (b) Direction of the Original Magnetic Field(the field not created by any current in the loop) ---Select---into the pageout of the pageclockwisecounterclockwise (c) Change in magnetic flux for loopaftert= 0 s ---Select---increasingdecreasingthe flux is constant at this time (d) Direction of theInducedMagnetic Fieldaftert= 0 s
(at the loop's center) ---Select---into the pageout of the pageclockwisecounterclockwisethere is no induced magnetic field at this time (e) Direction of the Induced Current through the loopaftert= 0 s ---Select---into the pageout of the pageclockwisecounterclockwisethere is no induced current at this time
Explanation / Answer
A: There is no current since there is no induced field yet and there is no battery attached B: The dots indicate the field is coming out at you; out of the page C: Since the field is decreasing, the flux is decreasing D: If the magnetic field is DECREASING, the induced field goes in the same direction - out of the page (If INCREASING flux, it goes in the OPPOSITE direction) E: Since the induced field is coming out of the page, the current is to the right. Use the bottom of the triangle and the right hand rule
