Em Fields

[wolram]

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?

[Tide]

What exactly do you mean by "interfere?"

[wolram]

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.

[Integral]

The resulting field will be a superposition of the 2 fields, it is not possible for them to exist separately.

Thankyou Integral.
