Question: What are the dimensions of magnetic flux?
- a) M²L²T⁻¹A⁻¹
- b) M²L⁻²T⁻¹A
- c) M²L²T⁻²A
- d) M²L²T⁻²A⁻¹
ANSWER: d) M²L²T⁻²A⁻¹
EXPLANATION:
The dimensions of magnetic flux are d) M²L²T⁻²A⁻¹. Magnetic flux is a measure of the total magnetic field passing through a given surface. It is defined as the product of the magnetic field strength (B) and the area (A) perpendicular to the magnetic field.
The dimensions of magnetic field strength (B) are given by the dimensions of force per unit electric charge (M * T⁻² * A⁻¹). The dimensions of area (A) are L².
Multiplying the dimensions of magnetic field strength (M * T⁻² * A⁻¹) by the dimensions of area (L²) gives us M²L²T⁻²A⁻¹, which represents the dimensions of magnetic flux.
