4. Two wires carry $1\mathrm{A}$ and $0.5\mathrm{A}$ currents as shown in the figure below. i. Find the magnitude and direction of the magnetic field at point P? ii. If you place another $15\mathrm{cm}$ long parallel wire at point $P$ that carries a current of $1.5\mathrm{A}$ to right, what would be the magnitude and direction of the force acting on the newly added wire.
