Question

Use Lenz's law to determine whether the induced current in the resistor R is from A to B or from B to A in the following configurations:

(1) a magnet with south side pointing down is entering a coil attached to a resistor with A coming before B if you go clockwise

(2) a magnet with north side leaving a coil attached to above resistor

(3) a magnet with north side entering the above coil

(4) a magnet with south side entering the coil like above but it is flipped (like it is starting to wind from bottom instead of top)

Explanation / Answer

1) from A to B ...since flux is decreasing it opposes the change in flux...so clockwise current 2)from A to B 3)from B to A 4)no current
