A circular coil of radius \( 8.0 \, \text{cm} \) \( 20 \) turns is rotated about its vertical diameter with an angular speed of \( 50 \, \text{rad s}^{-1} \) in a uniform horizontal magnetic field of \( 3.0 \times 10^{-2} \, \text{T} \). The maximum emf induced the coil will be __________ \( \times 10^{-2} \) volt (rounded off to the nearest integer).
