Electromagnetic induction The purpose of this exercise is to determine the direction of the induced current in a circular loop by two different methods. Consider a circular conducting loop of radius r = 10 cm and resistance R=222. The loop is placed in a uniform magnetic field B. 1) Document 4 shows three different cases. 1st case The plane of the loop is perpendicular to the magnetic field lines of B. 2nd case The plane of the loop is paralle! to the magnetic field lines of B. Doc. 4 3rd case The plane of the loop is perpendicular to the magnetic field lines of B Match each of the following sentences 1, 2 and 3 to its appropriate case. Justify. Sentence 1: The magnetic flux through the loop is zero. Sentence 2: The magnetic flux through the loop is positive. Sentence 3: The magnetic flux through the loop is negative. 2) Consider the first case of document 4. During the time interval [0.2 s], the value B of the magnetic field B decreases with time according to the relation: B=-0.04 +0.S (SI) 2.1) A current is induced in the loop during the time interval [0.2s]. Justify. 2.2) Apply Lenz's law in order to specify the direction of the induced current. 2.3) Determine the expression of the magnetic flux crossing the loop as a function of time. 2.4) Deduce the value of the induced electromotive force e . 2.5) The current carried by the loop is given by the relation i = R Deduce the value and the direction of i>. 2.6) Compare the direction of the induced current obtained in part (2.5) to that obtained in part (2.2).
