The plane of the coil should along the magnetic meridian. Therefore it is set in such a way that the compass needle and plane of the coil must be in the same plane. Only then magnetic field due to current flow will automatically perpendicular to the magnetic needle( I.e) horizontal component of earth's magnetic field) as per tangent law. I hope you are satisfied with my answer Sir❤
Thank you sir 🙏
Thank you so much this video very helpful for us
Sir one vedio made for the resolving power of telescope
Thank you Sir.. It's very useful to me Sir..
Thank you so much sir!
Tomorrow for me exam sir and now I'm watching ❤️ thank you ❤️
Thank you so much sir for explaining
Very use ful thanku
Thank you sir so helpful for preparation
thank you
சார் வாய்ஸ் நல்லா இருக்கு. டேன்ஞ்சன்ட் கால்வனா மீட்டர் எப்படி வைக்கனும் சொல்லுங்க
Videoவின் முற்பகுதியை கவனிக்கவும்
why is the needle perpendicular to the plane of the coil?, it should be in the place of the coil i suppose correct me if i'm wrong

@@physics20246 Ok. Thanks for the reply
Super sir
How did you find the radius
By measuring the circumference of the coil, (2pir), radius can be measured
Thank you sir
Sir, the value for 50 turns is not coming
Less current must be allowed to pass through tangent galvanometer coil
