Q1:
A long cylindrical conductor of radius R carries a uniformly flowing current I as shown in the
figure. Find an expression for the magnetic field magnitude B
a)
at a distance r < R and
b)
at a distance r > R, measured from the axis
Q2:
Figure shows a circular arc of wire of radius R, which carries a current I. Find the magnitude and direction
of the magnetic field at the center of the circular arc using the
Biot-Savart law
.
