Two long parallel wires lay on a table, both oriented in the north-south direction and separated by a distance of 24 cm. Each wire initially carries a current of 2.7 A towards the north. Consider the magnetic field at a point P that is on the table and located exactly halfway between the two wires. Which of the following actions will cause the magnitude of the magnetic field at point P to decrease compared to its initial value? (Choose all that apply) O Halve the current in the left wire only. O Halve the current in both the wires. O Double the current in both wires. O Halve the current in the right wire only. None of these actions will cause the magnetic field at point P to decrease
