The magnetic ±eld lines running through the middle region of a solenoid have their sense determined the direction of the thumb used with: a) a right-hand rule in which the ±ngers curl in the direction of current ²ow. b) a left-hand rule in which the ±ngers curl in the direction of current ²ow. c) a right-hand rule in which the ±ngers curl in the opposite to the direction of current ²ow. d) wind speed. e) guesswork. 030 qmult 00420 1 4 5 easy deducto-memory: magnetic material Extra keywords: mathematical physics 15. “Let’s play Jeopardy ! For \$100, the answer is: A material in which the atomic-scale magnetic dipoles can (but not necessarily do) align to create a strong net macroscopic magnetic ±eld.” What is a/an , Alex? a) electric material
