Question

A conductor rod AB moves parallel to x - axis in a uniform magnetic field, pointing in the positive X - direction. The end A of the rod gets:

• A. Positively charged
• B. Negatively charged
• C. Neutral
• D. First positively charged and then negatively charged.

Answer 1

The correct option is A Positively charged

As, in the shown fig, a conducting rod $AB$ moves parallel to $X-$ axis in a uniform magnetic field, pointing in the positive $Y-$ direction. The end $A$ of the rod gets positively charged-

Hence the current induced in both the coils will flow clockwise when seen from the magnet side.
