Question

Imagine that you are sitting in a chamber with your back 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?short answer.

Answer 1

direction of magnetic field will be inside the page

i found this by using fleming's left hand rule which states that if we strech our thumb, forefinger, and middle finger of our left hand perpendicular to each other in such a way that fore finger points the direction of magnetic field and middle finger points the direction of current then thumb will represent the direction of force.

Answer 2

$\huge \red{ANSWER}$

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.
