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
