358537 A solenoid has 2000 turns wound over a length of \(0.30\;m\). The area of its cross-section is \(1.2 \times {10^{ - 3}}\;{m^2}\). Around its central section, a coil of 300 turn is wound. If an initial current of \(2\;A\) in the solenoid is reversed in \(0.25\;s\), then the emf induced in the coil is
358538 Two coils \(A\) and \(B\) having turns 300 and 600 respectively are placed near each other, on passing a current of 3.0 ampere in \(A\), the flux linked with \(A\,{\text{is}}\,1.2 \times {10^{ - 4}}\) weber and with \(B\,{\text{it}}\,{\text{is}}\,9.0 \times {10^{ - 5}}\) weber. The mutual inductance of the system is:
