Solution:
(A)
‌Bab=‌‌‌ (out of the plane) ‌‌Bbcd=‌‌(2π)‌ (in the plane) ‌‌Bde=‌‌‌ (out of the plane) ‌Hence magnetic field at
O is
‌B0=−‌‌+‌‌(2π)−‌‌‌B0=‌‌(π−1)........‌ (III) ‌ (B)
‌Bab=‌‌‌ (out of the plane) ‌‌Bbcd=‌‌(π)‌ (out of the plane) ‌‌Bde=‌‌‌ (out of theplane) ‌Hence magnetic field at
O is
‌B0=‌‌+‌‌(π)+‌‌‌B0=‌‌(π+2)...‌. (I) ‌ (C)
Bab=‌‌ (in the plane)
Bbcd=‌‌(π) (in the plane)
Bde=0 (at the axis)
Hence magnetic field at
O is
B0=‌‌(1+π)... (D)
Bab=0 (at the axis)
Bbcd=‌‌(π) (out of the plane)
Bde=0 (at the axis)
Hence magnetic field at
O is
B0=‌...
