I discovered that a DC motor generates electricity. This is not the all of what I found. Basically a coil of copper rotates in the magnetic field when we pass electric current through the motor. Please underline the sentence "the copper coil rotates in the magnetic field". Thus the coil must generate electricity. Where does this electricity goes. The most interesting thing is that electricity is generated but also electromagnetic signals are generated. However all this is at a smaller scale. the current generated is very low.
