Magneto Ignition System Concepts

The video tutorial explains the magneto ignition system used in small gasoline engines. It covers the components, types, construction, and working of the system. The magneto ignition system is compact and requires low maintenance but produces less voltage at low speeds. The video also discusses the advantages and disadvantages of the system.

What is the primary function of a magneto in the ignition system?

• To distribute electrical energy

• To generate electrical energy

Which component in the magneto ignition system is responsible for switching the system on or off?

• Contact breaker

• Ignition switch

• Capacitor

• Distributor

In an armature rotating type magneto, which part remains stationary?

• Capacitor

• Distributor

• Magnet

• Armature

What is the role of the contact breaker in the magneto ignition system?

• To establish and break the circuit

• To generate spark

• To rotate the magnet

• To store charge

How is the secondary winding connected in the magneto ignition system?
