Question 7 options:
a. Weigh the nail first while before turning the current on and again while the current was on.
b. Put the nail in water before turning the current on and again after turning the current off.
c. Examine the nail under a microscope before turning the current on and again after turning the current off.
d. See if iron filings will stick to the nail before turning the current on and again while the current was on.
