What happens when a current flows through a metallic wire near a compass needle?
Answer
The compass needle gets deflected because the current-carrying wire behaves like a magnet.
जब एक कम्पास की सुई के पास एक धातु के तार से धारा प्रवाहित होती है तो क्या होता है?
Answer
कम्पास की सुई विचलित हो जाती है क्योंकि विद्युत प्रवाह ले जाने वाला तार एक चुंबक की तरह व्यवहार करता है।…
Why does a compass needle deflect near a current-carrying wire?
Answer
An electric current produces a magnetic field around the wire. The compass needle aligns itself with that field, so it changes direction.
धारा-वाहक तार के पास कम्पास की सुई क्यों विचलित होती है?
Answer
विद्युत धारा तार के चारों ओर एक चुम्बकीय क्षेत्र उत्पन्न करती है। कम्पास की सुई उस क्षेत्र के साथ संरेखित हो जाती है, इसलिए उसकी दिशा बदल जाती है।…
Who first discovered the magnetic effect of electric current?
Answer
Hans Christian Oersted discovered in 1820 that a compass needle got deflected when an electric current passed through a nearby metallic wire.
विद्युत धारा के चुंबकीय प्रभाव की खोज सबसे पहले किसने की थी?
Answer
हंस क्रिश्चियन ओर्स्टेड ने 1820 में पाया कि जब पास के एक धातु के तार से विद्युत प्रवाह गुजरता है तो एक कम्पास की सुई विचलित हो जाती है।…
