Magnetic & Electric Fields: A Cycle of Change?

Click For Summary
SUMMARY

A changing magnetic field generates a non-conservative electric field, as established by Maxwell's equations. When the magnetic field accelerates, indicated by a non-zero second derivative, the electric field also undergoes change. This dynamic relationship implies that a changing electric field can produce a magnetic field, leading to a continuous cycle of electromagnetic wave propagation. The example of B=e^t illustrates the mathematical representation of this phenomenon.

A changing magnetic field creates a non conservative electric field. If the changing magnetic field is accelerating(2nd derivative in non-zero) the electric field must also be changing. Would this mean that the changing electric field is producing a magnetic field.

Depending on the order of derivative this could continue indefinitely.

B=e^t for example...
