Unit-2: Steady Magnetic Field
For: B.E. / B.Tech (ECE, EE, EEE) 1. Steady Magnetic Field Steady magnetic field wo magnetic field hota hai jo time ke sath change nahi hota । Ye normally DC current ke karan produce hota hai। 👉 Example: current carrying conductor, solenoid, toroid. 2. Magnetic Field Strength (H) Magnetic field strength H magnetic field ki intensity batata hai। Symbol: H Unit: Ampere/meter (A/m) H mainly current aur conductor ki geometry par depend karta hai। 3. Magnetic Flux Density (B) Magnetic flux density B actual magnetic field ko show karta hai jo medium ke andar hota hai। Symbol: B Unit: Tesla (Wb/m²) Relation B = μH 4. Magnetomotive Force (MMF) MMF magnetic circuit me flux ko drive karne wali force hoti hai। Formula MMF = N × I N = number of turns I = current 👉 MMF electric circuit ke EMF ke equivalent hota hai। 5. Ampere’s Circuital Law Statement Closed path ke along magnetic field intensity ka line integral enclosed current ke equal ...
