Question

Which orientation gives maximum motional EMF?

विकल्प

• \[\vec{v}\perp\vec{B}\perp\vec{l}\], all mutually perpendicular

• \[\vec{v}\parallel\vec{l}\]

• \[\vec{v}\parallel\vec{B}\parallel\vec{l}\]

• \[\vec{v}\parallel\vec{B}\]

Answer 1

Maximum EMF occurs when velocity, magnetic field, and length of conductor are all mutually perpendicular. This orientation provides the required perpendicular velocity component.
