Question

# If a conducting rod $$AB$$ placed in a uniform magnetic field pointing in positive z-direction, moves parallel to y-axis, then end $$A$$ of the rod will be

A
Neutral
B
Positively charged
C
Negatively charged
D
None of these

Solution

## The correct option is B Positively chargedAs conducting rod $$AB$$ moves parallel to y-axis in uniform magnetic field pointing in positive z-direction, then according to Flemings left hand rule, the electrons in the rod suffer's a force towards end $$B$$. Hence, the end $$A$$ the rod will positively charged. Physics
