Gce Model Questions Vol1 2025 Physics Question 10
Practice objective / multiple choice question 10 from the 2025 Gce Model Questions Vol1 Physics examination.
A rectangular conducting loop of width \(w = 0.10\,\text{m}\) and length \(l = 0.30\,\text{m}\) moves at a constant speed \(v = 2.0\,\text{m s}^{-1}\) into a uniform magnetic field \(B = 0.5\,\text{T}\) directed into the page. The loop has a total resistance of \(0.20\,\Omega\). When the loop is positioned so that exactly half of its width has entered the field, determine (a) the magnitude of the induced emf, (b) the magnitude of the magnetic force acting on the loop, and (c) the mechanical power that must be supplied to keep the loop moving at constant speed at that instant.
