In each of the following, give the direction of the thing askedabout, or “zero†if it’s zero. Explain your choices.(a) [1 pts.]The magnetic field between the poles of this magnet.(b) [4 pts.]The magnetic field produced by this wire (carrying current in thedirection of the arrow) at the point marked “×â€(c) [5 pts.] Thetorque (clockwise or counterclockwise) on this current loop Theline with the arrow pointing up and right is a wire that is abovethe page,the line with the arrow pointing down and left is a wirethat is below the page,current flows out of the page in the bottomwire, into the page in the top wire.The magnetic field pointstoward the right.(d) [4 pts.] The emf (clockwise orcounterclockwise, or zero) induced in this square loop of wireattached to a pendulum, as it swings into the magnetic field. Thefield is directed into the page.(e) [4 pts.] The emf induced in thesame loop when it is going through the bottom of its swing,completelyin the magnetic field.(f) [4 pts.] The emf induced in thesame loop as it swings up out of the magnetic field.(g) [4 pts.]The emf induced in the same loop if it is hanging straight down atrest in the magnetic field.(h) [4 pts.] The emf induced in the sameloop if it is hanging straight down at rest in the magnetic fieldand then we suddenly turn the magnetic field off.
