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.
