The space to the right of the y axis in (Figure 1) contains a uniform magnetic field of unknown magnitude that points in the positive z direction. As a conducting square loop placed in the xy plane (oriented with its horizontal and vertical sides parallel to the xx and yy axes) moves to the right across the y axis at a constant speed of 2.0 m/s, a 0.42-V emf is induced in the loop. If the side length of the loop is 0.30 mm, what is the magnitude of the magnetic field? B=?
