    Em Field
AI Thread Summary
A small electromagnetic (EM) field can coexist with a larger EM field, but they cannot exist completely independently. The larger field will influence the smaller one, resulting in a superposition of both fields. The term "interfere" refers to the larger field affecting the characteristics of the smaller field. Ultimately, while both fields can be present simultaneously, the smaller field cannot exist in isolation from the larger one. Understanding this interaction is crucial for applications in electromagnetism.

Sorry if this question is basic.
Can a small EM field be superimposed into a large EM field without
the larger one interfering with the small one?
 
Physics news on Phys.org
What exactly do you mean by "interfere?"
 
Tide
I mean, the larger field can have no effect on the smaller field.
and that it can exist in isolation to the the larger field.
 
The resulting field will be a superposition of the 2 fields, it is not possible for them to exist separately.
 
Thankyou Integral.
 

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
