(a)Look at the following matchstick pattern of squares (Fig 11.6). The squares are not separate. Two neighbouring squares have a common matchstick. Observe the patterns and find the rule that gives the number of matchsticks in terms of the number of squares. (Hint: If you remove the vertical stick at the end, you will get a pattern of Cs.)(c)

List 'the factors on which the magnetic field produced by a current carrying straight conductor depends. State the rule which gives the direction of its magnetic field. Draw the pattern of magnetic field lines due to a straight current carrying field lines due to a stright current carrying conductor.
