प्रश्न
Describe how you will locate a current-carrying wire concealed in a wall.
उत्तर
We know that a current-carrying wire produces magnetic field. Therefore, we can locate a current-carrying wire concealed in a wall by detecting the magnetic field produced by the wire. It is done with the help of a compass.
