Igcse Model Questions Vol1 2025 Physics Question 27
Practice objective / multiple choice question 27 from the 2025 Igcse Model Questions Vol1 Physics examination.
A rectangular coil of 30 turns, each side \(0.10\ \text{m}\) long, is pulled at a constant speed into a uniform magnetic field of strength \(0.5\ \text{T}\) that is perpendicular to the plane of the coil. The field region is \(0.20\ \text{m}\) wide. While the coil is half inside the field, the induced emf measured across the coil is \(0.75\ \text{V}\).\n\n(a) Determine the speed at which the coil is being pulled.\n(b) If the same coil is pulled with the same speed but the magnetic field strength is doubled, what is the maximum emf induced? Give your answers to three significant figures.
