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

A) They should exit the box at N and enter at S.  

C) They should be put inside the box so the two ends join.

E) They should form loops outside of the box over the top, bottom, and sides of the box.

The correct answer is (a), (c) and (e).

Explanation:

Properties of magnetic field lines.

coil wire, increase current, put iron inside the coil

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
