Electromagnetism MCQs

Permeance is to reluctance as conductance is to

According to steinmetz hysteresis law,hysteresis loss in a material is proportional to

The transformer cores operating at microwavefrequency range, are usually made of

the time averaged Poynting vector is

A plane electromagnetic wave propagating in free space in incident normally on a large slab of loss-less, nonmagnetic, dielectric material with e> Co. Maxima and minima are observed when the electric field is measured in front of the slab. The maximum electric field is found to be 5 times the minimum field. The intrinsic impedance of the medium should be

The 'magnetic field intensity vector of a plane wave is given by

where a y denotes the unit vector is y direction. The wave is propagating with a phase velocity

55 (V x P) ? ds, where P is a vector, is equal to

The wave is
