Igcse Model Questions Vol1 2017 Physics Question 12
Practice objective / multiple choice question 12 from the 2017 Igcse Model Questions Vol1 Physics examination.
A rectangular coil of 30 turns, each side \(0.10\ \text{m}\), is initially lying completely within a uniform magnetic field of magnitude \(B = 0.5\ \text{T}\), perpendicular to the plane of the coil. The coil is pulled out of the field at constant speed so that it is completely out after \(0.20\ \text{s}\). The coil has a resistance of \(2.0\ \Omega\).\n\n(a) Calculate the average induced emf in the coil during the motion.\n(b) Determine the total electrical energy dissipated as heat in the coil.\n(c) State, with a brief explanation, how the mechanical work done in pulling the coil out compares with the electrical energy dissipated.
