Neco Model Questions Vol1 2023 Physics Question 48
Practice objective / multiple choice question 48 from the 2023 Neco Model Questions Vol1 Physics examination.
A rectangular conducting loop of resistance \(5\ \Omega\) has width \(0.12\ \text{m}\) and vertical side length \(0.20\ \text{m}\). The loop moves with constant speed \(0.5\ \text{m s}^{-1}\) into a region of uniform magnetic field \(B = 0.8\ \text{T}\) directed into the page. When exactly half of the loop's area is inside the field, what is the magnitude of the magnetic force (in newtons, expressed in scientific notation with two significant figures) acting on the vertical side that lies within the field?
