Igcse Model Questions Vol1 2017 Physics Question 21
Practice objective / multiple choice question 21 from the 2017 Igcse Model Questions Vol1 Physics examination.
A rectangular conducting loop of resistance \(4\ \Omega\) has vertical sides of length \(0.05\ \text{m}\) and horizontal sides of length \(0.10\ \text{m}\). It is pulled at constant speed into a uniform magnetic field of magnitude \(0.8\ \text{T}\) that is directed into the page. When the loop is half inside the field, the magnetic force on the portion of the loop that is within the field is measured to be \(0.020\ \text{N}\). Assuming the induced current is clockwise, determine the speed of the loop in \(\text{m s}^{-1}\).
