The wire ABC shown in figure forms an equilateral triangle. Find the magnetic field B at the centre O of the triangle assuming the wire to be uniform. `

Text Solution

Verified by Experts

the magnetic field at P due to AB and BD is equal to the magneitc field at P due to AC and CD in magnitude but opposite in direction.
Hence net magnetic field = 0.
