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 as

A 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.
