JEE Main 2025 Physics question
If B is magnetic field and μ0 is permeability of free space, then the dimensions of (B/μ0) is
Answer: (2)
Solution
B = μ0ni, so B/μ0 = ni, dimensions = [n][i] = L⁻¹A.
If B is magnetic field and μ0 is permeability of free space, then the dimensions of (B/μ0) is
B = μ0ni, so B/μ0 = ni, dimensions = [n][i] = L⁻¹A.
