Consider the current carrying conductor arranged in a circular form as shown in
the Fig. 7.6.1.

•
The
at the centre of the circular loop is to be obtained. The
conductor carries the direct current I.
•
Consider the differential length
at a point 1.
•
The direction of
at a point 1 is tangential to the circular
conductor at point 1.

Using
the definition of cross product,

•
According to Biot-Savart law, the differential magnetic field intensity
at point P is,

•
The flux
at centre of the circular conductor carrying direct current
I, placed in a free space is given by,

Review Question
1. Derive an expression for the flux density at the centre of a
circular loop carrying current I.
