Let x be the voltage at the upper junction and 0 at the lower and r be the resiatnce.
Hence applying KCL at junction.
(x + 10 – 10)/r + (x)/r + (x – 10 + 10)/r = 0
x/r + x/r + x/r = 0
3x/r = 0
x = 0 volt.
 
In whole circuit the net emf is 0 hence no current is flowing in the circuit and therefore, also there will be 0 magnetic foeld at point P.
