a student made an electromagnet using a battery electrical tape and metal wire. she wanted to see what the effect would be if she switched the side of the battery she connected each end of the wire to. which of the following would be a correct conclusion?
a. switching the side of the battery each end of the wire is connected to will have no effect.
b. switching the side of the battery each end of the wire is connected to will increase the electromagnetic force of the wire.**
c. switching the side of the battery each end of the wire is connected to will decrease the electromagnetic force of the wire.
d. switching the side of the battery each end of the wire is connected to will reverse the magnetic poles of the wire.

Hey, come on, if you reverse the direction of the current you reverse the direction of the magnetic field produced !
switching the electrical polarity
also switches the magnetic polarity
also switches the magnetic polarity
so its D??
Yes, the answer is D (I just took this quiz and got it right).
D, does anyone here go to NCCA?
