Activity 13.7 Class 10 Science Chapter 13
·
Take a small aluminium
rod AB (of about 5 cm). using two connecting wires suspend it horizontally from
a stand as shown in the figure.
·
Place a strong horseshoe
magnet in such a way that the rod lies between the two poles with the magnetic
field directed upwards. For this put the north pole of the magnet vertically below
and the south pole vertically above the aluminium rod.
·
Connect the aluminium rod
in series with a battery, a key and a rheostat.
·
Now pass a current through
the aluminium rod from end B to end A.
·
What do you observe? It is
observed that the rod is displaced towards the left. You will notice that the
rod gets displaced.
·
Reverse the direction of
current flowing through displacement. It is now towards the right.
·
Why does the rod get
displaced?

Activity 13.7 Class 10 Science Observation
An aluminium rod placed
in a magnetic field gets displaced upward(right) and downward(left)when current
is passed through it.
Activity 13.7 Class 10 Science Explanation
An aluminium rod is placed
between the poles of a horseshoe magnet, when an electric current is passed
through the rod, a magnetic
field is produced
around the rod.
So, the rod experience
a force in the magnetic field of the horseshoe magnet and moves
upward.
When the direction
of the current is reversed, the rod moves downward.
The direction of
force experienced by the current carrying conductor placed in a magnetic field can
be given by Fleming’s Left Hand Rule.
Activity 13.7 Class 10 Science Conclusion
The activity 13.7 shows that a current carrying conductor experience
a force in a magnetic field and the direction of the force depends on the direction
of (i) electric current and (ii) magnetic field
