Question
In the drawings, loop 1 has initially a current I_1 (source not shown). Indicate with arrows (cw or ccw) the direction of the induced current in loop 2 in the following situations. Also answer if the loops attract or repel as a consequence of the induction. (a) Current I_1 is CCW and increasing: Loops attract or repel? ______ (b) Current I_1, is CCW and decreasing Attract or repel? ______ (c) Current I_1 is CW and increasing: Loops attract or repel? ________ (d) Current I_1 is CW and decreasing Loops attract or repel? __________ (e) Current I_1 is again CCW but constant. Loop 1 approaches loop 2 Mark the induced current in loop 2. Attract or repel? ______ (f) Do the same as in (e) but with loop 1 getting away from loop 2 Attract or repel? _______Explanation / Answer
Lenz's law : The direction of induced current in sch a way that it opposes the change in mgnetic flux that generated it.
a) repel
b) attract
c) repel
d) attract
e) the direction of induced current will be CW
repel
f) the direction of induced current will be CCW
attract
