Summary
It is shown that direct-action electrodynamics cannot be generalized to include magnetic monopoles. Consequently, experimental searches for magnetic monopoles constitute a test of the theory.
Riassunto
Si dimostra che l'elettrodinamica ad azione diretta non può essere generalizzata ad includere monopoli magnetici. Di conseguenza, le ricerche sperimentali costituiscono una riprova della teoria.
Резюме
Показывается, что электродинамика прямого действия не может быть обобщена, чтобы включить магнитные монополи. Следовательно, экспериментальные поиски магнитных монополей представляют проверку теории.

We could avoid a contradiction by assuming that no charged particle ever intersects a magnetic monopole. However,F. Rohrlich (Phys. Rev.,150, 1104 (1966)) and others (see ref. (17)T. Yan:Phys. Rev.,160, 1182 (1967)) have shown that, in order to impose such a boundary condition, it is necessary to relax the assumption of locality of the action;i. e. the action would have to contain more information than is available in the particle paths.
