Academic text (1996) -
As Wigner noted in the introduction to his monumental opus, Group Theory and its Application to the Quantum Mechanics of Atomic Spectra, published in 1931, "There is great reluctance among physicists towards accepting group theoretical arguments."
Academic text (1995) -
The reluctance of the material to allow magnetic flux to pass through it affects the performance of the circuit.
-
In a magnetic circuit, high reluctance indicates a strong opposition to the flow of magnetic lines of force.
Synonyms

Etymology
Reluctance in physics uses the same roots re- 'back' and luct 'struggle', so a helpful way to remember it is as a magnetic kind of 'resistance' that 'pulls back' the magnetic field. That's why higher reluctance makes it harder for the magnetic field to pass through a material, much like electrical resistance slows electric current.
