Gce Model Questions Vol1 2022 Physics Question 40
Practice objective / multiple choice question 40 from the 2022 Gce Model Questions Vol1 Physics examination.
A long solenoid 0.50 m in length has 200 turns and carries a steady current of \(3.0\ \text{A}\). Its magnetic field inside is uniform and given by \(B=\mu_0 n I\) where \(n\) is the turn density. A rectangular conducting loop of width \(w=0.10\ \text{m}\) and height \(h=0.20\ \text{m}\) is pulled perpendicularly into the solenoid at a constant speed \(v\). When the loop is half‑inside the solenoid, the measured induced emf in the loop is \(0.12\ \text{V}\). Determine the speed \(v\) of the loop.
