Avertical wire carries a current straight upward (toward the sky) in a region where the magnetic field vector points horizontally toward the north. what is the direction of the magnetic force on this current-carrying wire due to the magnetic field?

When is a current produced? when the terminals of an electrochemical cell are connected by a wire if the electric circuit is opened in an electrochemical cell if the electrolyte is removed from an electrochemical cell when the electrodes are reversed in an electrochemical cell
