A wire is bent into three circular segment of radius `r = 10 cm` as shown in. Each segment is a quadrant of a circle `ab` lying in the `x-y` plane, `bc` lying in the `y-z` plane and `ca` lying in the `z-x` plane.
(a) if a magnetic field `B` points in the positive `x` direction, what is the magnitude of the emf developed in the wire when `B` increases at the rate of `3 mTs^(-1)`?
(b) What is the direction of the current in the segment `bc`.

Three identical wires are bent into semi-circular arcs to each of radius R . These arcs are connected with each other to form a closed mesh such that one of tham lies in x-y plane, one in y-z plane and the other in z-x plane as shown in. In the region of space, a uniform magnetic field of induction vec(B) = B_(0)(hat(i) + hat(j)) exists, whose magnitude increases at a constant rate dB//dt = alpha . Calculate the magnitude of emf induced in the mesh and mark the direction of flow of induced current in the mesh.
