Question:

Two currents create the total magnetic field at C. The direction of the top current is given and the bottom current is unknown. Due to the top current only, the magnitudes of the x and y components of the magnetic field at location C are given below. Which of the following statements is / are true IF the amount of current in the bottom wire is the same as in the top wire? Bx (horizontal) = 0.221T By (vertical) = 0.152T

◯ If the bottom current points out of the screen, it can cancel the magnetic field in the x direction

◯ If the bottom current points into of the screen, it can cancel the magnetic field in the x direction

◯ If the bottom current points out of the screen, it can cancel the magnetic field in the y direction

◯ If the bottom current points into of the screen, it can cancel the magnetic field in the y direction

◯ It is not possible to cancel either the x or y components of the magnetic field at C if the current in the bottom wire is the same magnitude as the current in the top wire
