Provide an answer to the following question.
Imagine that you are standing facing north. An electron beam moves horizontally from south to north and is deflected towards the east. What is the direction of the magnetic field?
Answer:
The electron beam travels horizontally from south to north and is deflected towards the east due to the magnetic field. The direction of conventional current is . Therefore, the current flows . Since the electron beam is deflected towards the east, the direction of force is towards the .
. Hence, the magnetic field is directed .
The direction of the magnetic field, force and current can be determined by the.
Hence, according to , the thumb represents the and the middle finger represents the , then the will be given by the direction of the forefinger.
