Question 15

A movable metal strip in an automatic parcel gate carries a current perpendicular to the page. Electrons in the strip drift into the page, and the magnetic force on the strip acts to the right. The north and south poles of a magnet are positioned one above and one below the strip. Which gives the direction of conventional current and the arrangement of the poles?

A

Conventional current into the page; north pole above and south pole below

B

Conventional current into the page; south pole above and north pole below

C

Conventional current out of the page; north pole above and south pole below
