|dw:1334906434547:dw|Is it like this\?

@Ishaan94 bhai, u r rite......

Matlab qudrant ke centre point pe jahaan dono radius lines mil rahe hain, right?

@apoorvk bhaijan, yes u r rite. But I think the question is wrong. Let me post anther one.

Find the magnetic field induction at the center "O".

@apoorvk , @Ishaan94 bhaiyajan, please answer me. 2 more questions still there.

|dw:1334909020335:dw| yehi na?

15. apoorvk

at centre point?

Yes, apoorv bhai, Ur diagram is correct. please solve at the earliest.

17. apoorvk

To jo linear sections hain, unke kaaran B zero hi rahega Centre point pe. Ab do semicircles hain. radius R and R/2. dono keliye magnetic centre point pe nikaalenge. Ampere's circuital law padha hai? Apply that and find out the B

Arre bhai, I don't know which formulae to apply. Please solve it by using the formuale, post all formulae regarding how to find magnetic field in different circuits. Please bhai. Post some sample questions of each type as to where we should apply which formula and find out.

|dw:1334909634188:dw| Isko lekin aise samjhaane se nahi samjhoge. NCERT hai 12th class ki? agar nahi hai toh net se download karo, and fourth chapter mein ek chhota sa section hai. use padh lo, clear ho jayega funda.

20. apoorvk

Is formula ka matlab hai ki, The net current enclosed in a circular loop of length 'l', produces a magnetic field of magnitude 'B'.

21. apoorvk

**rather the net current passing through (within/between) a loop.
