The image shows three independent turns with "a" radius each trough which a stationary current passes i=i0. If the turns are at a "b" distance from the center of each other, determine.a) the electric field vector in the point "p" placed at a d=a distance from the center of the turn Nº 1, when b = a, and when
b) If a fourth turn is added with radius = a/4, with an stationary current I=2i at a distance d/2 from the Nº 1 turn on the same axis, calculate the magnetic flow of the system on the last turn, the inductance and the magnetic energy stored by the turn (take b=a for this calculations)
