She powered the coil. It became a magnet, repelling the permanent magnet, and the motor jerked to life. This was the : a current-carrying wire in a magnetic field experiences a force .

Suddenly, the bulb got blazing hot and died. “Too much current,” Grandfather said. “Remember : V = I × R . For a fixed resistor, if voltage (V) goes up, current (I) goes up. But here, heat increases resistance, creating a non-ohmic failure.” She powered the coil
