Answer:
The
magnetic field pattern due to a circular coil is shown in the given figure. At
every point of current carrying circular loop the concentric circles
representing the magnetic field around it becomes larger and larger as we move
away from the wire. At the centre of the loop the field appears as straight
line.
The magnetic field produced by current carrying circular
wire at a given point, depend on
(i) Amount of current flowing through the wire The
strength of magnetic field (B) due to current carrying circular wire is
directly proportional to the amount of current (J) flowing through it.
i.e., ...(i)
(ii) Number of turns of the circular wire The strength of
the magnetic field due to current carrying wire is directly proportional to the
number of turns (N)oi the wire.
i.e., ....(ii)
If there is a circular coil having n turns, the field
produced is n times as large as that produced by a single turn. It happens
because the current in each circular turn has same direction and the field due
to each turn just adds up.
