In the figure, a 130 -turn coil of radius \( 2.0 \mathrm{~cm} \) and resistance \( 6.3 \Omega \) is coaxial with a solenoid of 300 turns/cm and diameter \( 3.4 \mathrm{~cm} \). The solenoid current drops from \( 2.1 \mathrm{~A} \) to zero in time interval \( \Delta t=23 \mathrm{~ms} \). What current is induced in amperes in the coil during \( \Delta t \) ? Number Units
