प्रश्न
AB is a current carrying conductor in the plane of the paper as shown in Figure. What are the directions of magnetic fields produced by it at points P and Q? Given r1 > r2, where will the strength of the magnetic field be larger?

उत्तर
By applying Right-hand thumb rule, the direction of the Magnetic field is into the plane of the paper at P and coming out from the plane of paper at point Q.
The magnitude of magnetic field B is inversely proportional to distance r.
Now, r1 > r2, or point Q is closer than point P, so the magnetic field is stronger at point Q and weaker at point P.
