Question

A straight conductor AC of finite length is placed perpendicular to an infinitely long straight conductor B (Fig.). Conductor AC moves on metal guides in a direction parallel to B and remains perpendicular to B. What is the direction of the current induced in AC when the direction of motion of AC is the same as the direction of the current in Bl What will be the direction of the current if AC is moved in the opposite direction?

Answer 1

If the conductor is situated above the magnet, then, when the magnet is rotated to the west, the current in the conductor flows from north to south; when the magnet is rotated to the east, the current flows from south to north. If the conductor is below the magnet, then in the first case, the current flows from south to north, and in the second case, from north to south.
