B) , The figure shows a coil and a permanent magnet that is moving relative to it. In which of the cases will an electric current NOT be induced? (The arrow → indicates the direction of motion of the magnet, D), In which of the experiments is NO current induced in the metal ring?, 0,7 А, What is the effective (rms) value I of the alternating current whose graph is shown in the figure?, 1, The figure shows a graph of an alternating voltage (the dependence of the voltage u , 2, The figures show experiments in which a permanent magnet is moved toward or away from a coil. In which of the shown experiments is a current induced in the coil? (the answer is 2 numbers), 3, How many seconds is the period of the alternating voltage?.
