C. Toward you

Step-by-step explanation:

  • The Left Hand Rule is a mnemonic device used to determine the direction of the magnetic field, current, or force in a conductor. The thumb, forefinger, and middle finger of the left hand are held perpendicular to each other, with the forefinger pointing in the direction of the magnetic field, the middle finger in the direction of the current, and the thumb in the direction of the force.

In this case, if the current points down, then the middle finger points down. If the field is to the left, then the forefinger points to the left. To satisfy the left hand rule, the thumb must point towards you, which indicates that the motion is towards you. Therefore, the motion is towards you.
