In this video we are going to discuss on
Maxwell's right hand grip rule
It decides
the direction of magnetic field lines
produced by a current-carrying conductor
Suppose, this is our current-carrying conductor
which is carrying current from left to right.
So due to this current a magnetic field is being created
around this wire
and this rule gives the direction of that magnetic field.
This rule states that
if a conductor carrying current is held in the right hand
This current carrying conductor.
I am holding that conductor with my right hand
such that as that
the thumb is pointed in the direction of current
so my thumb is pointing in the direction of current
So, as the current is flowing from left to right
and my thumb is pointing towards
That means my thumb is pointing from left to right.
So this is the direction.
Then the direction in which
my fingers encircle the wire
So my fingers, the other four fingers,
give the direction of the
magnetic lines of force or you can say
magnetic field lines around the wire
that means- magnetic field lines
around the wire will be in direction
this.
So this will be the direction of magnetic
field lines
So, if we put a magnetic needle
near this conductor,
what will happen?
As the magnetic field lines will be
in this direction
from bottom to up,
and as we know that the north pole of a magnet
goes along the magnetic field lines,
so this north pole will be deflected towards
this direction
and the south pole will go in
the opposite direction
That means, due to this current-carrying conductor
when the current is flowing from this point to that point,
due to the magnetic field lines which is flowing from
downwards to upwards ,
the magnetic needle will be deflected in this manner
You can compare this with
Ampere's swimming rule.
As we discussed in Ampere's swimming rule,
according to this rule,
if a person is swimming with his face
downwards, looking at the magnetic needle,
such that the current enters his feet
and leaves from his head
then the north pole of the magnetic needle
will get deflected towards
his left hand
So the deflection of this needle
will be in this direction
