Q. No 10: Imagine that you are sitting in a chamber with your
back to one wall. An electron beam, moving horizontally from back wall towards
the front wall, is deflected by a strong magnetic field to your right side.
What is the direction of magnetic field?
Ans:
The direction of magnetic field is given by Fleming’s left hand
rule. The direction of electric current will be from front wall to back wall as
it is opposite to the direction of electron. Now since the direction of force
is towards the right side. Hence by applying Fleming’s left hand rule, we can conclude
that the magnetic field inside the chamber is in downward direction.
How the magnetic field is in downward direction?
