Here, $$A=500cm2=500$$×$$10$$−$$4m2N=1000$$,$$B=0.4G=0.4$$×$$10$$−$$4Tt=110sWhen$$ the coil is held perpendicular to the filed, the normal to the plane of the coil makes an angle of $$00$$  with the field B.∴ Initial flux, ϕ$$1=BAcos0$$∘$$=BA$$ final flux,  ϕ$$2=BAcos180$$∘$$=$$−BAAverage induced emf, ε$$=$$−Nϕ$$2$$−ϕ$$1t=$$−N−BA−$$BAt=2NBAt=2$$×$$1000$$×$$0.4$$×$$10$$−$$4$$×$$500$$×$$10$$−$$41/10=$$ $$0.04$$ V
