Suppose that an electromagnet uses a coil 2.0  m in diameter made from square copper wire 2.0  mm on a side; the power supply produces 35  V at a maximum power output of 1.0  kW. (a) How many turns are needed to run the power supply at maximum power? (b) What is the magnetic field strength at the center of the coil? (c) If you use a greater number of turns and this same power supply, will a greater magnetic field result? Explain. | Numerade
