Question

According to what law, an induced current acts to produce an opposing flux. Bios-Savart's Lons's Amper's Faraday's A place flies at constant speed due North through the earth's magnetic field that has components that point both North and vertically down. In this situation, The left side of the place becomes positively charged. the right side of the place becomes positively charged. the top of the place becomes positively charged. the bottem of the plane becomes positively charged. Consider a square loop, which is fully immersed in a constant magnetic field B. A 'motional' emf is induced in the loop, when the loop Rotates in the field along an axis perpendicular to the field. Is at rest, but the B field then suddenly changes. Moves with constant velocity v perpendicular to B, it leaves the field region all of the above
