125. MAGNETIC LINES FOR CURRENT
LOOP

126. Magnetic Lines for a Current Loop:
We know that the magnetic field at a point P on the axis is
given by Eq. (10.53) as
𝐵𝑧 =
𝜇0𝐼𝑅2
2 z2 + 𝑅2 3/2
As a special case, the field at the centre of the loop is
obtained from the above equation by letting 𝑧 = 0 :
𝐵0 =
𝜇0𝐼
2𝑅
For a coil of N turns,
𝐵 =
𝜇0𝑁𝐼
2𝑅
The magnetic field lines from a circular loop are depicted
in Fig. 10.20. The direction of the field is as per the right
hand thumb rule: Curl the palm of your right hand along
the circular wire with the fingers in the direction of the
current. The stretched right hand thumb then gives the
direction of the magnetic field (Fig. 10.21). Thus, the
upper part of the loop seen in Fig. 10.20 may be regarded
as the North pole and the lower part as the South pole of a
bar magnet.

127. The magnetic moment 𝑚 of a circular loop is defined
as 𝑚 = 𝐼𝐴, where 𝐴 is a vector of magnitude 𝐴 and
direction perpendicular to 𝐴. Using Eq. (10.56),
∴ 𝐵𝑧 =
𝜇0
2𝜋
𝑚
𝑧3
𝐵𝑧 =
𝜇0
4𝜋
2𝑚
𝑧3
Note that 𝐵𝑧 and 𝑚 are in the same direction,
perpendicular to the plane of the loop.
Using electrostatic analogue,
𝐸 =

4𝜋𝜀0𝑧3
,
which is the electric field at an axial point of an
electric dipole.
