AS 5055 C F-stype Solenoid Relay

The solenoid relay contains of two coils of wire that are wrapped around a moveable core. The solenoid relay acts as a switch to close the electrical connection and connects the starter motor to the vehicle's battery.
The solenoid replay plays a crucial role in your car/machine. Every time you start the car/machine, the solenoid turns and sets the engine running. But that only happens when you have a working starter. To ensure a healthy starting system, you need to be conversant with how a starter relay works.
The starter solenoid has two primary functions in a car's/machine starting system. Firstly,  it is responsible for pushing the drive pinion gear into engagement with the ring gear teeth. This engagement is what allows the starter solenoid to turn the engine over during starting.
Secondly, it operates as a relay switch to energize the starter motor. This means it connects the battery's heavy amperage to the starter motor when the ignition key is turned.
So, the correct answer to the question
