acoil of self inductance L is connected at the one end of two rails as shown in the figure a connector of length l and mass m can slide freely over the two parallel read the entire setup is placed in a magnetic field of induction be going into the page at instant t= o i initial velocity Vo is imparted to it and as a result of that it is start moving along x-axis the displacement of the connector is represented by the figure

AB is a current carrying conductor in the plane of the paper as shown in the figure below. (i) What is the direction of the magnetic field produced by it at point ‘X’? Write the statement of the rule used to find the direction of field lines. (ii) If the polarity of the battery connected to the wire is reversed, how would the direction of the magnetic field be changed? (iii) Point ‘X’ is at a distance r1 and point ‘Y’ is at a distance r2 (r1
