The magnetic field midway between two parallel current carrying wires, carrying currents I and 2i in same direction is B. If the current in the wire with current I is switched off, the magnetic field will become

Two parallel wires carrying current I and 2I in same direction have magnetic field B at the midpoint between them. If the current 2I is switched off, the magnetic field at that point will be

Two parallel wires carrying current I and 2I have magnetic field B at the mid point between them. If the current 2I is switched off, the magnetic field at that point will be :

The magnetic field at a point midway between two parallel long wires carrying currents in the same direction is 10 mu T. If the direction of the smaller current among them is reversed, the field becomes 30 mu T . The ratio of the larger to the smaller current in them is
