    Two parallel long wires carry currents i1i_1 and i2i_2 with i1>i2i_1 > i_2. When the currents are in the same direction, the magnetic field at a point midway between the wires is 10 μT10\ \mu\mathrm{T}. If the direction of i2i_2 is reversed then the field becomes 30 μT30\ \mu\mathrm{T}. The ratio i1i2\dfrac{i_1}{i_2}
