Mag field in a current carrying square

Click For Summary
SUMMARY

The discussion centers on the magnetic field at the center of a current-carrying square loop. Participants assert that the magnetic field is not zero due to the contributions from segments AD and BC, which do not cancel each other out. The magnetic field generated by segment ABC is directed upward, while the field from segment ADC is directed downward, leading to a net magnetic field at the center. The confusion arises from the interpretation of the question and the diagram provided.

The Attempt at a Solution



answer says that its 0
I am guessing there is some problem in question ... the field won't be 0 at center .. it can't be ... field due to AB and CD gets canceled but field of AD and BC is in same direction and won't get canceled ...

magnetic field due to AD and BC are getting cancelled, assuming both paths ADC and ABC have same resistances for currents in both paths to be same.
magnetic field due to ABC is upward and due to ADC is downward at the centre.
 
i guess you are getting the question wrong ...

the figure is from what the question says "previous question" ... its not exactly of the question i gave ...
