Magnetic Circuits: Inductance Design and Calculation

Welcome to Video 4 of the Magnetic Circuits Course: Inductance Design and Calculation. In this lesson, we move beyond theory and into practical design, showing how inductance is not only calculated, but also validated and optimised in real-world conditions. Whether you're a student, engineer, or enthusiast, this video will help you connect electromagnetic fundamentals with hands-on implementation. ⏱ What you’ll learn in this video: 00:00 – Introduction 00:40 – Understanding Faraday’s Law and its role in inductance 02:30 – What is Self-Inductance? 04:46 – Challenges of winding coils directly onto the core 06:05 – Best practices for effective coil winding 07:19 – Example 1: Step-by-step inductance calculation 08:43 – Example 2: Verifying inductance using calculation, FEA, and measurement 11:30 – Simulation walkthrough using FEMM 4.2 (FEA method) 12:45 – Practical measurement techniques 14:44 – Comparative insights: Calculated vs FEA vs Measured results 16:07 – Example 3: Designing inductance with real-world constraints 🔗 Previous Videos in the Course: 📘 Video 1: Course Introduction and Sources of Magnetic Fields    • Magnetic circuits: Course Introduction   📘 Video 2: What is a Magnetic Circuit    • What is the Magnetic Circuit?   📘 Video 3: Analogy Between Magnetic and Electric Circuits    • Analogy between Magnetic Circuit and Elect...   🧪 FEMM 4.2 Tutorial (Step-by-Step):    • Step-by-Step FEMM 4.2 (Electrostatic & Ele...   🔍 By the end of this video, you’ll understand not just how to calculate inductance—but how to design, validate, and refine it using analytical, simulation, and experimental approaches. 📌 Don’t forget to like, comment, and subscribe for more deep dives into magnetic circuits and engineering fundamentals! #Inductance #MagneticCircuits #ElectricalEngineering #FEA #EngineeringDesign
