STANDARD Physics Magnetic Permeability MCQ Question
Type: MCQ-conceptual-Medium
A solenoid has a core of a substance with relative Permeability 600. What is the magnetic permeability of the given substance?
A
20π × 10⁻⁵ N A⁻²
B
21π × 10⁻⁵ N A⁻²
C
22π × 10⁻⁵ N A⁻²
D
24π × 10⁻⁵ N A⁻²
Correct Answer
Option D
Detailed Explanation
The magnetic permeability μ is given by μ = μᵣμ₀. With μᵣ = 600 and μ₀ = 4π × 10⁻⁷ N A⁻², the calculation gives μ = 600 × 4π × 10⁻⁷ = 24π × 10⁻⁵ N A⁻².
