Скачать или смотреть q30-magnetic field when same wire is bent into a coil with different number of turns

In this video, we’ll explore how the magnetic field changes when a straight current-carrying wire is bent into a circular coil — one of the most conceptual topics in Electromagnetism, frequently asked in JEE Mains, NEET, and Boards ⚡

You’ll learn:
✅ Comparison of magnetic field of a straight wire and circular coil
✅ Dependence of magnetic field on number of turns (N) and radius (R)
✅ Derivation of the relation B ∝ N / R for a circular loop
✅ Calculation of magnetic field at the center and on the axis of a coil
✅ Effect of increasing or decreasing the number of turns on total magnetic field
✅ Solved JEE & NEET PYQs and tricky conceptual questions

By the end of this video, you’ll clearly understand how bending the same wire into different numbers of turns affects the magnetic field strength, and how to apply this in competitive exam problems.

📚 Watch till the end for full theory + derivations + PYQs + conceptual understanding!
