Question

A metallic block carrying current $I$ is subjected to uniform $B$ as shown in fig.

• A. Electron experiences force $eVB$ in the positive $z-$direction hence face $ABCD$ is at lower potential
• B. Electron experiences force $eVB$ in the negative $z-$direction hence face $EGHF$ is at lower potential
• C. Transverse electric exist $E_H=VB$
• D. None of these

Answer 1

The correct option is C Transverse electric exist $E_H=VB$

Transverse electric exist,

$E_H=V.B$

Using the Hall Effect.
