Question

In a p-n junction with open ends,
(a) there is no systematic motion of charge carries
(b) holes and conduction electrons systematically go from the p-side to n-side and from the n-side to p-side respectively
(c) there is no net charge transfer between the two sides
(d) there is a constant electric field near the junction.

In factories, scrap iron is separated from the heap of waste materials by using big electromagnets fitted to a crane. When a such a crane is lowered on to the heap of waste materials, then the scrap iron objects present in the heap, cling to the electromagnet.
