Neco Model Questions Vol1 2024 Physics Question 10
Practice objective / multiple choice question 10 from the 2024 Neco Model Questions Vol1 Physics examination.
A single‑turn rectangular coil of dimensions \(0.10\ \text{m} \times 0.20\ \text{m}\) rotates with an angular speed of \(\omega = 300\ \text{rad s}^{-1}\) in a uniform magnetic field of magnitude \(B = 0.5\ \text{T}\). The axis of rotation is perpendicular to the field and passes through the centre of the coil. The coil has a resistance of \(2\ \Omega\). (i) What is the maximum induced emf in the coil? (ii) What is the average electrical power dissipated in the coil over one complete rotation? Express your answers in volts and watts respectively.
