A 711 turn circular loop coil 19.7 centimeter in diameter is initially aligned therefore that its axis is parallel to Earth's magnetic field. In 2.45 milliseconds the coil is flipped thus that its axis is perpendicular to Earth's magnetic field.
If an average voltage of 0.245 Volt is there by induced in the coil, find what is the value of Earth's magnetic field at that location? Answer in units of μT.
