1.	PQ is a cwrent carrying conductor in the plane of the paper as shown in the fig. Mention the direction of magnetic fields produced by it at points A and B. Given : r_(1) lt r_(2r) ,where will the strength of the magnetic field be larger ? Justify your answer in each case.
Answer» SOLUTION :STRENGTH of magnetic field will be larger at A as the strength of magnetic field decreases when the distance is increased direction of MAGNETICFIELD lines at A as well as B is anticlockwise because field lines are concentric circles and direction is determined by Right HAND thumb rule.
