Question 11 (5 points] (5 marks) In the diagram below, the magnet is being pulled out of the coil of wire. This causes a current to be induced in the wire. ( a. Draw an arrow on the wire to indicate the direction in which the current moves. b. Indicate which side of the coil of wire will act as a North Pole and which will act as a South Pole. c. Describe 2 ways in which the induced current could be increased. Question 12 (3 points) (3 marks} Consider the generator below. The part of the wire labeled A is connected to slip ring A, the part of the wire labeled B is connected to slip ring B. a. Is the current flowing in through A and out through B, or the other way around? b. Explain why it is AC electricity that is produced. c. What effect will reversing the two magnets have on the generator and the electricity that is produced? Question 13 (2 points) (2 marks] Electricity is transmitted in high-tension wires with a voltage of 500 W. The voltage in our homes is only 120 V. Explain why we don't just transmit the electricity at 120 V to save the cost and effort needed to stepdown the voltage. Question 15 {2 points] (3 marks) When a certain electromagnet contains 1000 turns in its length and carries a current of 10 A, it can lift a 200 kg load. If the electromagnet is rewound such that it contains 5000 turns, but only carries a current of 5 A, how large a load could it lift
