Electromagnetic Induction Quiz

The force is directly proportional to $ ext{sin}( heta)$; it is maximum when $ heta = 90^ ext{o}$ and zero when $ heta = 0^ ext{o}$.

Doubling the current will double the force experienced by the conductor.

The force will also be doubled if the length of the conductor is doubled.
