(a)
List two factors on which the magnitude of magnetic field produced by a current carrying straight conductor depends.
(b)
State the rule which determines the direction of magnetic field in the above case.
(c)
Draw the pattern of magnetic field lines produced in this case.
Marking-scheme solution
(a) Two factors:
(i) Current passing through the conductor
(ii) Distance of the point from the conductor
(b) Statement of Right-hand thumb rule- If we stretch the thumb of our right hand in the direction of current, then the direction in which the fingers will curl is the direction of magnetic field lines.
