Question

Multiple-Choice Homework Problem 12.6 The two finite solenoids in the figure are moving toward one another. The left solenoid is powered by a battery producing a nearly constant cur rent. Is a current induced in the right solenoid? If a current is induced, what is the direction of the induced current in the right solenoid as the current flows through the resistor R2 connected to the right solenoid? Select One of the Following: (a) The current is zero. (b) to the left of the page (c) to the right of the page Multiple-Choice Homework Problem 12.7 The magnetic field at the right is increasing in strength. What is the direction of the induced current in the conducting loop (dark circle) shown on the diagram? Select One of the Following: (a) clockwise (b) counterclockwise (c) There is no induced current.

Explanation / Answer

1. to the right of the page

2.clockwise {  As the magnetic fiel d increase flux = B.A start increasing therefore an induce current flow into the loop.the current is induce due to increase into the field therefore it will try to decrease the field this can happen is induced current produce an inward field into the loop, therefore clockwise current appear into the loop. }
