Electrons are emitted from a conductor when a conductor is?

C- bombarded by high speed electrons

That's like saying "water comes out of a pipe when water is poured into the pipe" Conductors don't EMIT electrons (any more than any material), but they allow electrons to flow freely within...

YES

Whenever a charge passes through a conductor, a magnetic field is produced. Hence, whenever a current carrying conductor is placed in a magnetic filed, it will experience a force whose direction is...

Yes, because the neutral conductor will transfer its electrons to the postitively charged conductor.
