Gce Model Questions Vol1 2017 Physics Question 32
Practice objective / multiple choice question 32 from the 2017 Gce Model Questions Vol1 Physics examination.
A rectangular conducting loop of width \( w = 0.20 \;\text{m} \) and length \( l = 0.50 \;\text{m} \) moves with constant speed \( v = 0.10 \;\text{m s}^{-1} \) into a region where a magnetic field varies linearly with distance \( x \) from the entry edge: \( B(x)=B_{0}\frac{x}{L} \) for \( 0\le x\le L \), with \( B_{0}=0.80 \;\text{T} \) and \( L=0.40 \;\text{m} \). The loop is initially outside the field. The circuit has resistance \( R=10 \;\Omega \). (i) Find the magnitude of the induced emf when the loop is just fully inside the field. (ii) Determine the total charge that passes through the circuit during the whole entry process.
