In the interial reference frame `K` there is a unifrom magentic field the induction `B`. Find the electric feidl strength in the frame `K'` which moves relative to the frame `K` with a non-relatistic veclocity `v`, with `v _|_ B`. To solve this problem, consider the forces acting an an imaginary charge in the frame `K'` is equal to zero.

What are interial frames ?

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' ?
