MHT CET 2024 Physics question
A particle carrying a charge equal to 100 times the charge on electron is rotating one rotation per second in a circular path of radius 0.8 m. The value of magnetic field produced at the centre will be ( =permeability of vacuum)
Answer: (B)
Solution
A revolving charge is equivalent to a current loop with A. The field at the centre of a circular loop is \dfrac{μ_0 I}{2r}\dfrac${μ_0× 1.6×
