Relative Permeability And Magnetic Field
A material has a relative permeability μr = 1.0000023. If this material is placed in a solenoid with current I, how will the magnetic field inside the material compare to the field that would exist in vacuum?
A
Unchanged since μr ≈ 1
B
Much stronger due to domain alignment
C
Slightly stronger by a factor of 1.0000023
D
Slightly weaker by a factor of 0.9999977
