Problem

A cylindrical copper shell of radius

0.10\,\text{m}

and negligible thickness is placed coaxially in a region where a uniform magnetic field along its axis changes at the rate

2\,\text{T\,s}^{-1}

. Assuming the field is perpendicular to the circular cross-section, find the magnitude of the emf induced around the circumference of the shell. a)

1.26\,\text{V}

0.020\,\text{V}

0.063\,\text{V}
