• Despite its name, emf doesn't really mean "force".
• Emf 🌩️ tells us about the energy transfers in a power source.

🤔 Think Like This: Imagine a water pump pushing water through pipes. Even though the pump isn’t “water force,” it's causing the water to move by giving it energy. Similarly, emf pushes electric charges by giving them energy!

• Electrical energy ➡️ another form (e.g., heat due to resistance).
• Another form ➡️ electrical energy (e.g., light to electricity in solar cells).

🌞 Real-World Example: When you use solar (photovoltaic) cells on a calculator, sunlight (radiant energy) gets converted into electricity!

• Emf comes into play when devices, like cells, transfer energy to electrons. How? Through chemical effects!
• But that's not the only way! Devices can convert energy into electricity via magnetic effects too.

🎤 Did You Know? Microphones, electrical generators, and dynamos all use this magic of converting energy into electricity. For instance, when you speak into a microphone, your voice (sound waves) gets converted into an electrical signal!
