What is the direction of the induced current in FIGURE Q

Short Answer
The direction of the induced current is determined as, a counterclockwise current creates the next force , which tends to tends flux inside the loop.

turn, diameter coil is made of diameter copper wire. A magnetic field is parallel to the axis of the coil. At what rate must increase to induce a current in the coil?
FIGURE shows a -cm-diameter loop with resistance around a -cm-diameter solenoid. The solenoid is cm long, has turns, and carries the current shown in the graph. A positive current is when seen from the left. Find the current in the loop at
You want to insert a loop of copper wire between the two permanent magnets in FIGURE Q30.2. Is there an attractive magnetic force that tends to pull the loop in, like a magnet pulls on a paper clip? Or do you need to push the loop in against a repulsive force? Explain
