(a) The pattern of magnetic field due to a current carrying wire depends upon the shape made by that wire. Justify.
(b) A current carrying straight wire AB is shown in the given diagram. Out of X, Y and Z on which point will the strength of magnetic field be maximum and why ?
Solution
(a)
1+1
(any two cases)
/
• Magnetic field pattern for a current carrying straight conductor-
concentric circles.
• Magnetic field pattern for a current carrying solenoid- magnetic
field lines similar to that of a bar magnet.
• Magnetic field pattern for a current carrying circular loop- a pair
of concentric circles with parallel straight lines at the centre.
(any two cases)
(b)
• At X.
• Magnetic field decreases as the distance from the conducting
wire increases.
