In an interial  reference  frame `K` there is only  magnetic  field with  induction `B = b (yl -x)//(x^(2) + y^(2))`, where `b` is a constane, `i` and  `j`  are the unit  vectors of the `x`  and `y` axes. Find the  elecric  field  strength  `E'`  in the  frame  `K'`  moving  relative to the frame  `K` with  a constatn non-relative  velocity `v = vk, k` is the  unit vector  of the z-axis. The  `z'`  axis is assumed  to coincule  with the `z` axis. What is the shape  of the field `E'` ?
