Two identical long solenoids share the same axis; one is slid inside the other so their bores coincide. Both carry the same current magnitude.
Case I: Currents in the same direction.
Case II: Currents in opposite directions.
Which statement best describes the resultant field far from the ends?
A) Case I: nearly double inside, almost zero outside; Case II: almost zero everywhere except small end regions. B) Case I: zero inside; Case II: doubled inside. C) Both cases: zero inside due to cancellation. D) Both cases: strong outside, weak inside.
