Waves emitted through a moving object as attained by an observer will be blueshifted (compressed) if approaching, redshifted (elongated) if receding. It takes place both in sound with electromagnetic phenomena, though it takes on different forms in each.
Figure shows the magnetic circuit of a relay. When each of the air gaps are 1.5mm wide find the mmf required to produce a flux density of 0.75 T in the air gaps. Use the B-
