A wire \( 88 \mathrm{~cm} \) long bent into a circular loop is placed perpendicular to the magnetic field of flux density \( 2.5 \mathrm{~Wb} \mathrm{~m}^{-2} \). Within \( 0.5 \mathrm{sec} \), the loop is changed into a square of each side \( 22 \mathrm{~cm} \) and flux density is increased to \( 3.0 \mathrm{~Wb} \mathrm{~m}^{-2} \). Calculate - the value of e.m.f. induced.https://bit.ly/YTAI_PWAP https://www.pw.live
