Neco 2017 Physics Question 46
Practice objective / multiple choice question 46 from the 2017 Neco Physics examination.
A rectangular coil of \(400\) turns, each turn having an area of \(2.0\times10^{-3}\,\text{m}^2\), is placed completely inside a uniform magnetic field of \(0.5\,\text{T}\) whose direction is perpendicular to the plane of the coil. The field region extends only over a length of \(0.20\,\text{m}\) along the direction of motion. The coil is pulled out of the field at a constant speed. While the coil is exiting, an average induced emf of \(2.0\,\text{V}\) is recorded. Assuming the portion of the coil still inside the field decreases linearly with time, determine the speed of the coil in \(\text{m s}^{-1}\).
