Question

imagine that you are sitting in a chamber with your back to one world and electron beam moving horizontally from back wall towards the phone work is deflected by strong magnetic field to your right side what is direction of magnetic field? ( movement of electron is opposite to current )

Answer 1

Right to you because the current is passing in front and back so it is right

Answer 2

$\huge \bold{ANSWER}$

Explanation:

The direction of the magnetic field is vertically downwards. The direction of current is from the front wall to the back wall because negatively charged electrons are moving from back wall to the front wall. The direction of magnetic force is rightward. Hence, using Fleming's left hand rule, it can be concluded that the direction of magnetic field inside the chamber is downward.
