Neco Model Questions Vol1 2024 Physics Question 41
Practice objective / multiple choice question 41 from the 2024 Neco Model Questions Vol1 Physics examination.
A long solenoid of length \(0.50\ \text{m}\) contains \(800\) turns and has a radius of \(2.0\ \text{cm}\). It carries a current that is increasing at a constant rate of \(3.0\ \text{A\,s}^{-1}\). The solenoid is placed in a uniform external magnetic field of \(0.20\ \text{T}\) directed perpendicular to its axis. A secondary coil of \(150\) turns is wound tightly around the solenoid; the secondary coil has a resistance of \(12\ \Omega\). Determine the magnitude of the induced current in the secondary coil at the instant described.
