Last updated: 6/24/2023

A circular conduction loop of radius ro and having resistance per unit length as shown in the figure is placed na magnetic field B which is constant in space and time The ends of the loop are crossed and pulled in pposite directions with a velocity v such that the loop always remains circular and the radius of the loop goes n decreasing then A B C Radius of the loop changes with r as r ro vt n EMF induced in the loop as a function of time is E 2Bv ro vt n Bv Current induced in the loop is I 2 By
