Magnetic field due to currentHard
Question
A long straight metal rod has a very long hole of radius ′a′ drilled parallel to the rod axis as shown in the figure. If the rod carries a current ′i′ find the value of magnetic induction on the axis of the hole, where OC = c
Options
A.
B.
C.
D.
Solution
Assuming there is positive and negative current through cavity (net current = 0)
Bc = B due to solid wireA(WITHOUT CAVITY) − Bdue to wire C =
+ 0
Bc = B due to solid wireA(WITHOUT CAVITY) − Bdue to wire C =
