Iposted this yesterday and i am still waiting in what way does a temporary magnet provide an advantage over a permanent magnet? a. a temporary magnet is stronger than a permanent magnet. b. a temporary magnet is larger than a permanent magnet. c. a temporary magnet uses less current than a permanent magnet. d. a temporary magnet allows the user to determine when it is magnetic

A temporary magnet allows the user to determine when it is magnetic and when it isn't.  

That's very useful if, for example, you want to pick up a bunch of small iron objects (such as nails or junked cars), move them over to somewhere else, and then DROP them.  This is easy to do if you have a magnet that you can turn on and turn off.

answer: the correct answer is   air pressure at the top of mount everest is higher than at the bottom of the grand canyon.
