PQ is a current carrying conductor in the plane of the paper as shown in thefigure below.(i) Find the directions of the magnetic fields produced by it at points R and S? (ii) Given r1> r2, where will the strength of the magnetic field be larger? Give reasons.(iii) If the polarity of the battery connected to the wire is reversed, how would the direction of the magnetic field be changed?(iv) Explain the rule that is used to find the direction of the magnetic field for a straight current carrying conductor. |
