What can you conclude about the compass deflection direction and magnitudes? Compasses work by pointing along magnetic field lines. Since the compass deflected this means that there is a magnetic field near the wire while current is running through it. Compasses work by pointing along the current direction. Anytime a compass is turned to a certain direction, there is a electric current nearby. Compasses always point to the North pole of Earth regardless the surrounding.Which of the following operation will NOT change an electromagnet's strength? Changing the number of turns in coil of wire Use an iron insert in the loops of wire Turn the coil of wire to the North-South direction
