Question

What happens to motional EMF if \[\vec{v}\parallel\vec{l}\]?

Options

• The magnetic field becomes zero

• No EMF (no effective length component)

• The EMF becomes ten times larger

• Maximum EMF

Answer 1

If velocity is parallel to the conductor's length, there is no effective length component for the stated motional emf arrangement. Consequently, no EMF appears across the ends.
