A. 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 motion is to the left, then the current must be flowing in the opposite direction, which is to the right. If the field points up, then the forefinger points up, and the middle finger must point to the right to satisfy the left hand rule. Therefore, the current is flowing towards you.
