APFIVE Relative Permeability And Magnetic Field
A material with a relative permeability of μr = 1.0000023 is placed inside a long solenoid. How does the magnetic field within the material compare to the magnetic field that would exist in a vacuum under identical conditions?
A
Slightly weaker by a factor of 0.9999977
B
Much stronger due to domain alignment
C
Unchanged since μr ≈ 1
D
Slightly stronger by a factor of 1.0000023
