Right Hand Grip Rule and Maxwells Screw Rule - Magnetic Effects of Electric Current Video Lecture - Class 10

the directions of the magnetic field can
be determined by two methods or two
rules
Maxwell's screw rule and the right hand
grip rules okay
personally I prefer the second one the
right hand grip rules okay I seldom use
a Maxwell school rule but anyway in stn
you still need to know
Maxwell screw rule okay because
sometimes in objective questions they
will draw the diagrams of Maxwell screw
rules and then they will ask you okay
which one is the correct use of Maxwell
screw rule so your student to know
Maxwell school rules even though if you
don't like Maxwell school rule you
student to know in my fusions again
usually I will use a right hand grip
Ruza to show you the directions of the
film so let's start with a right hand
grip rules right hand grip rules of
course they're from the name then you
should know that you should use your
right hand and don't use your left hand
side because a lot of students are
right-handed in exam okay so they use
their right hands to write when they see
a questions okay so straight away they
we use the left hand to find the field
that's not correct
so if your lab right-handed so if you
see the questions then you have to put
down your pen okay and then use your
right hand to find the directions of the
field make sure that you you use the
right hand okay so for this right hand
grip bruza you just imagine that this is
a wire okay this is wire so you use your
right hand to grip the wire okay to grip
the wire in this way and the tongue the
tongue shows the directions of the
current okay
the tumped shows the directions of the
corona so this is current and the other
four fingers show the directions of the
field so the tongue shows the directions
of the currents the other fingers show
the directions of the field so the C so
this one okay because the the the finger
shows that is anti-clockwise so the
field is anti-clockwise
the currents go up the currents go up
and then the fear is a counterclockwise
okay so that is how we use the right
hand grip rules to determine the
directions of the film then for the
Maxwell school rules so just imagine
that you have a screw the sharp end of
the screw shows the directions of the
current the directions of the current
then you try to imagine that if you want
to tighten a screw if you ever use these
to screw a screw drivers okay when you
want to tighten the screw we always turn
clockwise okay and that is the
directions of the film so this point to
the directions of the current and
returner we always turn clockwise for
screw if you want to tack down the screw
we always turn clockwise so that is the
directions of the film so that is how we
use a right hand grip rules or Maxwell's
screw rules to determine the directions
of the field we seal them you seldom use
this one again for me I actually I don't
like this method but you still see what
you need to know okay yeah you may come
out in objective questions that they
would like you to identify the
directions of the field by using Maxwell
school rules
