1.	Consider a circular loop of wirelying in the planeof the table . Letthe currentpass through the loop clockwise . Apply the Right-hand thumb ruleto findout the direction of the magnetic field inside and outside the loop.
Answer» Solution :Using the RIGHT - handthumb rule, the directionof the magnetic FIELD insdieand outsidethe cirularloopof wirecarrying anelectric currentcan be found. THISIS shown in thefollowingfigure . Thedotted magnetic field lines are perpendicularto theplaneof the PAPER . The front faceof the loop behaveas the south pole and theback face , i.e., the facetouchingthe plane of thetablebehaves as the NORTH pole .
