Question

think you are sitting in a chamber with your back to one ball and electron beam moving horizontally from backward towards the front wall is deflected by a strong magnetic field to your right side what is the direction of magnetic field

Answer 1

the magnetic field is on my right side

Answer 2

$\huge \mathbb{Answer}$

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.
