Determine the dimensions of magnetic dipole moment M . The defining equation is M = IA , where A is area and I is current.

Options

  1. ALTI
  2. BL^2TI
  3. CL^2I
  4. DLI

Correct answer

C. L^2I

Step-by-step solution

The defining equation for magnetic dipole moment is M = IA . The dimensional formula for current I is [I] . The dimensional formula for area A is [L^2] . Substituting these dimensions into the equation, we get: [M] = [I] [L^2] = [L^2I]
