Magnetic Field due to a Current through a Circular Loop Video Lecture - Class 10

magnetic field due to a current through
a circular loop we have so far
observed the pattern of the magnetic
fields lines produce around a current
carrying straight wire suppose the
street wire is bent in the form of a
circular loop and a current is passed
through it
how would the magnetic field lines look
like we know that the magnetic field
produced by a current carrying straight
wire depends inversely on the distance
from it
similarly at every point of a current
carrying circular loop the concentric
circles representing the magnetic field
around it would become larger and larger
as we move away from the wire have a
look at the figure
by the time we reach at the center of
the circular loop the arcs of these big
circles would appear as straight lines
every point on the wire carrying current
would give rise to the magnetic field
appearing as straight lines at the
center of the loop
by applying the right hand rule it is
easy to check that every section of the
wire contributes to the magnetic field
lines in the same direction within the
loop this rule is also called Maxwell's
corkscrew rule
if we consider ourselves driving a
corkscrew in the direction of the
current then the direction of the
corkscrew is the direction of the
magnetic field
