Igcse Model Questions Vol1 2021 Physics Question 17
Practice objective / multiple choice question 17 from the 2021 Igcse Model Questions Vol1 Physics examination.
A rectangular conducting loop of width \(0.10\ \text{m}\) and height \(0.20\ \text{m}\) lies in a uniform magnetic field of magnitude \(0.5\ \text{T}\) directed into the page. The loop is pulled to the right at a constant speed so that it leaves the field region. When the loop has moved such that exactly three‑quarters of its original area remains within the field, the induced emf measured around the loop is \(0.25\ \text{V}\). The total resistance of the loop is \(2\ \Omega\). (i) Find the speed of the loop. (ii) Determine the magnitude of the magnetic force acting on the vertical segment of the loop that is still inside the field at that instant.
