Layna and Aaron have made an electromagnet by coiling a copper wire around an iron nail, then connecting the wire to a battery, as seen in Figure 1. This causes electricity to flow through the coil, magnetizing the nail and creating a magnetic field. Electromagnet diagram. A coil of wire is wrapped around an iron nail and connected to a battery.

QUESTION: Layna says that they can increase the strength of their electromagnet by wrapping more coils of wire around the iron nail. Aaron says that they can increase the strength of the electromagnet by connecting a different battery to the wire.

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
