A toroid has a core of inner radius \(20 \mathrm{~cm}\) and outer radius \(22 \mathrm{~cm}\) around which 4200 turns of a wire are wound. If the current in the wire is \(10 \mathrm{~A}\). What is the magnetic field inside the core of toroid? 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
