Suppose you pull two opposite sides of the loop away from each other, such that the other two sides get closer, reducing the loop area. Suppose as you look down on the loop, the magnetic field also points downward through the loop. Which direction (clockwise or counterclockwise) does the induced current flow, from your perspective?

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
