Suppose a coil of 1000 turns of wire is wound around a book, and this book is lying on a table. The vertical component of earth's magnetic field is about `0.6 xx 10^(-4) Wb//m^(2)`. The area of the coil is `0.15 xx 0.20 m^(2)`. If this book is turned through `90^(@)` about a horizontal axis in 0.1 sec, what average emf will be induced in the coil?

Answer

0.018V
