Figure shows the path of an electron in a region of uniform magnetic field. The path consists of two straight sections, each between a pair of uniformly charged plates and two half circles. The electric field exists only between the plates

An electron does not suffer any deflection while passing through a region of uniform magnetic field. What is the direction of the magnetic field ?
