22. Biot -Savart's Law gives the fundamental concept of calculation of
magnetic field around a current carrying conductor.
a) Define Current element "idl" and also write expression of Biot-
Savart's Law at point P in vector form.
b)
Derive the expression of magnetic field due to finite long straight
conductor carrying current.
c)
A 40 cm long wire is bent in the form of square having its one
side 10cm, A current of 10 A is allowed to pass through the coil,
then calculate the magnetic field induction at the center of square
coil
