電話的接收會不會受到磁場的影響?

Although the propagation of electromagnetic waves is unaffected by magnetic field, the functioning of those elctronic components inside a telpehone set could be affected by strong magnetic field, unless the casing of the set is made of anti-magetic material to shield off the magnetic field lines.

會,因為電話的接收是靠無線電波,而無線電波是電磁波,所以也會受外在的磁場影響.
