JEE MainPhysicsElectromagnetic InductionMCQ+4 / −1
Consider a thin metallic sheet perpendicular to the plane of the paper moving with speed ‘v’ in a uniform magnetic field B going into the plane of the paper (See figure). If charge densities σ\sigmaσ 1 and σ\sigmaσ 2 are induced on the left and right surfaces, respectively, of the sheet then (ignore fringe effects) : JEE Main 2016 (Online) 10th April Morning Slot Physics - Electromagnetic Induction Question 106 English
