Now we will consider the time varying electric field. In any case, we have found a remarkable new aspect of electromagnetism. An em field solver for electric machines, transformers, actuators and other electromechanical devices. The concept of low frequency and slowlyvarying phenomena is relative to the situation at hand. The only way to have a looping electric field is a timevarying magnetic field, via induction, but we wont talk about that until midway through the course. Effect on dna synthesis article pdf available in science 2234638. Only in a nontimevarying case can electric and magnetic fields be considered as independent of each other. A timevarying electric field creates a magnetic field. Which means that a time changing magnetic field bt produces an electric field. Request pdf timevarying fields the static electric and magnetic fields have already. E, it has a property of circulation, its line integral about a general closed path. The shapemorphing mechanism using inhomogeneous electric fields within a sheet of elastomer is exemplified in fig. It solves static, frequencydomain, and timevarying electric fields.
