I’m not even sure abt telephone…if they are referring to the ear/mouth piece, think these are piezoelectric stuff.

Hi elkniwt

Thank you for the question. I learn something new today. I googled and found the write-up below. Latest stapler do come with magnet.
[quote]A regular stapler includes a base, a staple magazine, and a handle which are hinged for pivotal motion and wherein staples are pushed forward by a spring. Other types of stapler employ a magnet which has a similar function as a spring. Themagnet draws the staples beneath the staple ejector provided on the handle. In this type of stapler, the magnet must be securely attached to the stapler; however, occasionally the magnet occasionally comes off of the stapler, causing the stapler to stopfunctioning stapling operation.[/quote]

I really do not understand why schools ask such questions which are not common (or maybe I am a mountain tortoise?). If the purpose is to understand a concept, why can't they use common items? If we adults don't even know, how do we expect 9 - 10 year olds to know?
Sorry for ranting but the school questions do get me sometimes.

But one of my stapler does have a magnetic catch.


The expected answer is C and D. Pianos do not have magnets.

Hi acforfamily,

I wholeheartedly agree with you. Common staplers do not come with magnets. Even adults like me, (guess must be very out-dated) have not seen staplers with magnets, what to expect of the little ones. :roll:
