Two wires each carrying current i are shown. The magnetic field at P (midway
between the wires) is described by which statement?
(1) Magnetic fields are in opposite direction and net field is equal to zero.
(2) Magnetic fields due to two wires are in the same direction
(3) Magnetic fields are in opposite direct ion but net field is not zero
(4) magnetic fields are in the same direction and equal to two times the field
due to one wire.
