Flyback transformer is a source of high frequency electromagnetic field.
Axisymmetric problem of Transient magnetics
Ferrite permeability μ=1000,
Operation frequency f=1 kHz,
The transformer works in discontinuous mode, currents in windings are known:
Calculate the magnetic field distribution around flyback transformer during operation cycle.
Model may be defined and solved as a Transient Magnetic Analysis problem.
Magnetic field around the flyback transformer.
Magnetic flux density 1 cm away from the flyback transformer.
