If observer is in the side of magnet, then in the given case form S in the ring, it will give you clockwise direction
can you give me an idea of solving the parallel LC circuit? Also to find the phase difference between the I and E?

1st make a 3 line circuit in which ac source, resistor with an inductor and resistor with a capacitor will be there in the three lines then divide total current "I"
from AC into the two legs, equations will be
e = L di1/dt + i1R (1)
e =q2 / C + i2 R (2) here dq2 / dt = i2
now solve
