The dimensional formula for magnetic flux is:

1. [ML²T⁻²A⁻¹]
2. [ML²T⁻²A²]
3. [M⁰L²T⁻²A²]
4. [ML²T⁻¹A²]

Correct answer: [ML²T⁻²A⁻¹]

Solution

Magnetic flux (Φ) is given by the product of magnetic field (B) and area (A). The dimensional formula for B is [MT⁻²A⁻¹], and for area, it is [L²]. Multiplying these gives [ML²T⁻²A⁻¹].
