The magnetic field at a point between two parallel wires carrying currents in the same direction can be found using the formula: B = μ0*I/(2π*d) where B is the magnetic field, μ0 is the permeability of free space, I is the current, and d is the distance between the wires. For the current I₁, the magnetic field will be zero at a distance of: d = μ0*I/(2π*B) d = μ0*1/(2π*(1.2567*10^-6)*1)/(10^-2) d = 0.6667 cm Therefore, the magnetic field will be zero at a distance of 0.6667 cm from the wire carrying the current I₁.
