Question: Two infinitely long parallel wires carry equal current in same direction. The magnetic field at a mid point in between the two wires is [MP PMT 2001]
Options:
A) Twice the magnetic field produced due to each of the wires
B) Half of the magnetic field produced due to each of the wires
C) Square of the magnetic field produced due to each of the wires
D) Zero
Show Answer
