Explanation:

The characteristic of iron that would make it a bad material for the housing around a compass is that it could not be used because it can attracts the magnets in which compass it self is a form of magnet which can utilize the magnetic properties of the earth to give a reading reason been that Compass housings are often made of either brass, aluminium or plastic
