Consider an infinite one dimensional wire carrying a uniform current I as shown in the figure. A square loop of side a is initially placed such that the center of the loop is at a distance R from the wire, where R a 2 . The square loop is then moved rightwards with a uniform speed v as shown in the figure. What is the induced e m f in the loop as a function of time t ?
Options
