As a coil is removed from a magnetic field an emf is induced in the coil causing a current to flow within the coil. This current interacts with the magnetic field producing a force which
A)
acts at right angles to the coil's motion.
B)
acts in the direction of the coil's motion.
C)
causes the coil to tend to flip over.
D)
acts in the direction opposite to the coil's motion.
