Web90. A rectangular copper loop of mass 100 g and resistance 2.0Ω is in a region of uniform magnetic field of strength 3.0 T that is perpendicular to the area enclosed by the ring and horizontal to Earth's surface (see below). The width of the loop is a = 25 cm.The loop is let go from rest when it is at the edge of the nonzero magnetic field region. http://www.geomag.bgs.ac.uk/education/earthmag.html
