Sequence of relay switch operation for electric motor

Steps:

• Identify the logical flow: relay activation begins with an initial step (statement 5, likely power supply or relay initiation, though undefined).
• Follow with current entering the coil to magnetize the electromagnet (statement 1).
• Then, closing the primary circuit switch (statement 4) enables control current.
• Next, current flows in the secondary circuit to turn the motor (statement 2).
• Finally, the electromagnet attracts the armature (statement 3) to maintain the circuit.

Not enough information: Statement 5 is not provided, making full sequence ambiguous.

Final answer: Not enough information.
