Question

Suppose you’re sitting in a room facing one on the wall and electron beam moving horizontally from the bank goes to as the volume front of you and is deflected to your left what is the direction of magnetic field in the room ?

Answer 1

Answer:

the electron beam go downward after deflecting from wall

Answer 2

$\huge \tt{Answer}$

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.
