Igcse Model Questions Vol1 2022 Physics Question 36
Practice objective / multiple choice question 36 from the 2022 Igcse Model Questions Vol1 Physics examination.
Inside a long solenoid of length \(0.30\ \text{m}\) the current varies with time as \(I(t)=3t^{2}\) A, where \(t\) is in seconds. A single‑turn circular loop of radius \(0.10\ \text{m}\) is placed coaxially at the centre of the solenoid. The loop has a resistance of \(4\ \Omega\). At \(t = 2\ \text{s}\) the induced current in the loop is measured to be \(0.15\ \text{A}\). Determine the total number of turns in the solenoid.
