Expert Answer:

(a) When we rub soil or sand with magnet, we find some particles of soil or sand remain attached to it because the soil or sand particles contain some iron particles which stick to the magnet.

(b) No, the magnet will not show its properties if it is accidently dropped from some height because it loses its magnetic properties if it is heated, hammered or dropped from some height.
