Q1: A potential difference is developed across a current carrying metal strip when the strip is placed in a transverse magnetic field. The above effect is known asA Fermi's effect
B Photo electric effect
C Joule's effect
D
Hall's effect
ANS:D - Hall's effect If a current-carrying metallic conductor strip is located in a magnetic field B perpendicular to the direction of the current I, a transverse electrical field EH and a potential difference is produced so called Hall effect. |
