Hiro wants to model the magnetic field of a bar magnet using a shoe box and pipe cleaners. he labels the ends of the shoe box n and s. how should he position the pipe cleaners? check all letters that apply. a) they should exit the box at n and enter at s. b) they should exit the box at s and enter at n. c) they should be put inside the box so the two ends join. d) none should be put inside the box. e) they should form loops outside of the box over the top, bottom, and sides of the box. f) they should form loops outside of the box, but over only the sides of the box. g) mark this and return save and exit

true a, c, e

Explanation:

A magnet has continuous cheese field lines, this means that they must leave one point and reach another. In general they leave the North Pole and arrive at the South Pole.

The lines cover the entire space, its density at one point is the field intensity proportional, but there is no point if a field line.

Now we can review the statements of the exercise.

a) True. Is the right address

b) False. The address is incorrect

c) True. The lines are continuous regardless of the size of the magnet

d) False. There can be no point without field lines

e) True. The lines form lazaos that cover the entire space

f) False. It does not cover all the space
