An electric motor is an electrical machine that converts electrical energy into mechanical energy.
Electric motors work on the principal of the interaction between magnetic field electr-magnetism. A loop which is carrying the current is placed in a magnetic field. The loop will experience a torque. The torque starts rotating the coil and the propellers start to rotate when the current passes through the loop.
An electric motor is a slightly modified galvanometer. An electric motor current changes direction every time the coil makes a half revolution. Electric motors have greatly impacted the way of life. It made it possible to replace enormous human and animal toil by electric power all over the world.
it could be either or because it doesnt just depend on the height but it also depends on the pressure but then again the question didnt ask anything about the pressure so the answer should be true
