to use your left hand to determine the direction of the voltage developed in a moving conductor in a stationary magnetic field, you must point your? A) thumb in the direction of the magnetic flux. B)thumb in the direction of the electromagnetic force. C)forefinger in the direction of the lines of force. D)forefinger in the direction of the motion.
Refer to your text on this one. There are many left and right hand rules.
Answer C top of page 73
thank you I couldn't find that one either
Thank you for the page number I always want to see it for myself!!!!!

Without more information, it is not possible to answer your question. Please provide more details about the question you are asking.
To determine the direction of the voltage developed in a moving conductor in a stationary magnetic field using your left hand, here is a step-by-step process:
1. Extend your left hand with your thumb, forefinger, and middle finger pointing perpendicular to each other, forming a right angle between your thumb and forefinger.
2. Align your forefinger in the direction of the lines of force in the stationary magnetic field (Answer C).
3. Position your thumb to point in the direction of the motion of the conductor.
By following these steps, the direction your middle finger is pointing represents the direction of the voltage developed in the moving conductor.
Remember, this is known as the left-hand rule for determining the direction of the induced current or voltage in a conductor moving in a magnetic field. There are several other left and right-hand rules in physics that can help determine various phenomena.
