TS EAMCET · Physics · Magnetic Effects of Current
A conducting rod is moving towards right with a velocity ' \(\mathrm{V}\) ' in a uniform magnetic field ' \(\mathrm{B}\) '. If the direction of induced current ' \(\mathrm{i}\) ' is as shown in the figure, then the direction of ' \(\mathrm{B}\) ' is
- A in the plane of the paper towards right
- B in the plane of the paper towards left
- C perpendicular to the plane of the paper and into the paper
- D perpendicular to the plane of the paper and out of the paper
Answer & Solution
Correct Answer
(C) perpendicular to the plane of the paper and into the paper
Step-by-step Solution
Detailed explanation
By Fleming's Right-Hand Rule: Direction of \( \mathrm{V} \) (Thumb): Right Direction of \( \mathrm{i} \) (Middle finger): Down Therefore, direction of \( \mathrm{B} \) (Forefinger): Perpendicular to the plane of the paper and out of the paper.
