📘 Topic: Work Done in Rotating a Magnet in a Magnetic Field
🎯 Chapter: Magnetism and Matter – Class 12 Physics
📝 Exam Focus: Important for HTET Physics, CBSE Board, and other teaching/competitive exams

In this video, we solve a conceptual and numerical question based on the work done in rotating a magnetic dipole in a uniform magnetic field.
This question was asked in the HTET PGT Physics exam, and also aligns with Class 12 NCERT concepts.

✅ What You’ll Learn:

Concept of Magnetic Potential Energy

Derivation of Work Done = U_initial - U_final

Use of formula: W = pB(cosθ₁ - cosθ₂)

Application to real exam questions
