High reluctance material

WebWhat is reluctance in magnetic materials? a) Allows the buildup of magnetic flux b) Reduces the buildup of magnetic flux c) Resists the buildup of magnetic flux d) Increases the buildup of magnetic flux View Answer 10. High Reluctance affects the performance of magnetic materials. a) True b) False View Answer 11. WebReluctance is inversely proportional to permeability (µ). Iron cores have high permeability and, therefore, low reluctance. Air has a low permeability and, therefore, a high reluctance. Generally, different types of materials have different values of reluctance (Figure 25). Air gap is the air space between two poles of a magnet.
