The book says,
"when a length of copper wire PQ is moved downwards through the poles of two horizontal bar magnets as shown below. Compared to end Q, end P will have fewer electrons."
But isn't it the opposite? Using the left hand rule, for me it seems like the electrons will gather more on the end P - I mean, your thumb points downwards and index finger points right, and the middle finger points backwards which means that the electrons come towards you (the opposite direction to the conventional current).
# Also, would the situation be different if the copper wire is in a loop (continuous?)
Sorry about my horrible handwriting!
