Shape morphing through spatially varying electric fields. An em field solver for electric machines, transformers, actuators and other electromechanical devices. It solves static, frequencydomain, and timevarying electric fields. Now we will consider the time varying electric field. Pdf ferrohydrodynamics in timevarying magnetic fields. Only in a nontimevarying case can electric and magnetic fields be considered as independent of each other. Electrostatic fields are usually produced by static electric charges whereas magnetostatic fields are due to motion of electric charges with uniform velocity. In any case, we have found a remarkable new aspect of electromagnetism. View notes chapter 71timevarying fields and maxwel equations i2019 spring.
A timevarying electric field creates a magnetic field. 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. Which means that a time changing magnetic field bt produces an electric field. The concept of low frequency and slowlyvarying phenomena is relative to the situation at hand. What faraday found was that an electric field or electromotive force, emf was induced by a time varying magnetic flux. Chapter 71timevarying fields and maxwel equations i. Sbu intro physics labs, phy 122 electric field plotting lab. Reconfigurable shapemorphing dielectric elastomers using. Effect on dna synthesis article pdf available in science 2234638. Any disturbance timevariation of the electromagnetic field.
