To reverse motor direction, which action should be performed?

• A. Switch leads T1 and T3
• B. Swap the power supply leads L1 and L2
• C. Rewire the coil pair
• D. Ground the system

Answer: (A)

Reversing a DC motor’s direction comes from flipping the current in one of its windings, which changes the rotating magnetic field and the torque produced. Swapping the ends of the winding labeled T1 and T3 does exactly that: it reverses the current flow in that winding, so the motor spins in the opposite direction. Grounding is only for safety and does not affect rotation. While swapping the main supply leads might alter polarity in some setups, the intended and reliable way to reverse direction in this configuration is to switch T1 and T3.
