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.
so its D??
To determine the correct conclusion, we need to understand how an electromagnet works. An electromagnet is created by passing an electric current through a wire. The electric current generates a magnetic field around the wire, which produces the magnetic effect.
In this case, the student used a battery, electrical tape, and a metal wire to create the electromagnet. The battery provides the necessary electrical energy, and the metal wire acts as a conductive path for the electric current to flow.
Now, if the student switches the side of the battery that each end of the wire is connected to, it will essentially reverse the flow of electric current through the wire. This means that the direction of the magnetic field generated by the wire will also be reversed.
By reversing the direction of the magnetic field, the magnetic poles (north and south) of the electromagnet will also be reversed. Therefore, the correct conclusion would be:
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
