Use the right hand dynamo rule to predict which way the induced current flows through the conductor AB in diagrams (a) and (b) below (i) Diagram (a): Magnet stationary, conductor moves in the direction of the arrow. Induced current flows from (ii) Diagram (a): Magnet moves in the direction of the arrow, conductor stationary. Induced current flows from (iii) Diagram (b): Magnet stationary, conductor moves in the direction of the arrow. Induced current flows from (iv) Diagram (b): Magnet moves in the direction of the arrow, conductor stationary. Induced current flows from
