The dimensions of magnetic field in M, L, T and C (coulomb) is given as

1. [MLT⁻¹C⁻¹]
2. [MT²C⁻²]
3. [MT⁻¹C⁻¹]
4. [MT⁻²C⁻¹]

Correct answer: [MT⁻¹C⁻¹]

Solution

The magnetic field is defined in terms of force per unit charge and velocity, which leads to the dimensional formula of mass (M), time (T) to the power of -1, and charge (C) to the power of -1, resulting in [MT⁻¹C⁻¹].
