The north pole is on the left and the south pole is on the right. Correct!Both ends are south poles. 0 / 0.5 ptsQuestion 2The magnet moves as shown. The field of the magnet through the coil isto the left and the primary flux through the coil is decreasing. You Answeredto the right and the primary flux through the coil is increasing. orrect Answerto the right and the primary flux through the coil is decreasing. to the left and the primary flux through the coil is increasing. 1 / 1 ptsQuestion 3Consider what will happen when a bar magnet is pushed toward the coil. When the coil “feels” the changing magnetic field caused by the approach ofthe bar magnet, it will thereby become energized; a current will begin to flowthrough it, and the ammeter will register that current. This current is calledan induced current because it has been induced by the person pushing thebar magnet toward the coil. When the current flows, the coil again becomesan electromagnet. To determine which end of the coil is north and which
