A magnetic compass shows a deflection when placed near a current-carrying wire. How does the deflection of the compass get affected, if the current in thewire is increased ? Support your answer with a reason. |
| Answer» Solution :Ifthe current in the wire is INCREASED, the deflection increases. This is so as the magnetic field is DIRECTLY proportionalto the MAGNITUDE of currentpassing through the straight CONDUCTOR. This causes the COMPASS needleto deflectmore. | |
