Solenoid-1.png (1060×376) What is a Solenoid? A solenoid is a coil of wire wound in a cylindrical shape that generates a magnetic field when an electric current passes through it. It acts like an electromagnet and is commonly used in motors, relays, and inductors. What is Induced EMF? Electromotive Force (EMF) is the voltage generated when the magnetic flux through a coil changes. According to Faraday’s Law , a changing magnetic field induces an EMF, which is the principle behind transformers and electric generators. QUESTIONS (Try to solve these at your own first): 1.       A solenoid 1.30 m long and 2.60 cm in diameter carries a current of 18.0 A . The magnetic field inside the solenoid is 23.0 mT . Find the total length of the wire used to form the solenoid. 2.       A solenoid has 2000 turns uniformly wound over a length of 50 cm . If it carries a current of 5 A , find the...

  CppNotes - A Journey in C++ Learning When I got my hands on C++, I was in 7th or 8th grade, but I wanna give that credit to my elder brother for giving me that knowledge. Recently, When I started refreshing my C++ knowledge, I had no idea it would turn into something I could share with the world, maybe maybe maybe. My CppNotes repository is now a comprehensive collection of C++ resources;  a guide for beginners and intermediate programmers, with practical examples and real-world code snippets. Why CppNotes? It started as a personal project to refresh my C++ programming skills , but quickly grew into something that could help others too. I wanted to create a structured learning path , with topics ranging from basic arithmetic operations to object-oriented programming . Here’s what may find, Insha ALLAH: User Input: Handling user input in C++ Arithmetic Operations: Basic and complex calculations explained Control Flow: If-else and switch statements Loops: Mastering diffe...

Who Am I? Well, that's a really good question! I’m Bilal Ahmad Khan , also known as Mr. BILRED . From a young age, I’ve been deeply fascinated by technology, hacking, programming, and digital security . My passion led me to explore languages like Python, GoLang, and C++ , diving into malware analysis, web scraping, and ethical hacking . In short? I'm mostly self-taught! My Cybersecurity Fascination I’ve always wanted to understand how the hacker’s world operates . As a kid, I explored hacking knowledge, read books, followed videos, and built my own experience; learning not as a "course" or "degree," but as a way of life . Read that again! And if you're planning to dive into cybersecurity , here’s my "suggestion": Don’t ruin someone’s life. Life is too short, live it with modesty. Stay away from illegal stuff. Currently, I’m pursuing a Bachelor’s in Electrical Engineering at NUST , balancing academic life with real-world projects, content creati...
