Function: Does water affect an electromagnetic field?
Overview: Sound waves experience both drinks of water as well as air. As a matter of fact, they take a trip further and also faster in water than they do in the air. Just how about magnetism? Does it undergo water, also?
Theory: Water has no effect on Magnetism

Procedure: Ask an adult with scissors to remove the rounded part of a 2-liter bottle. Area a steel paper clip in all-time low of the bottle. Wrap a strip of concealing tape around one end of a six-sided, not round, pencil, and afterward number the sides. Compose “1” on the tape on one side, after that turn the pencil and also compose “2,” and so forth. Connect an item of concealing tape/ Tie the other end of the string to a magnet. Transform the pencil covering the string around it, and set it over the top of the plastic container. Slowly, lower the magnet right into the bottle. When the magnet is close adequate and also records the paper clip, quit! Notification of the number on the side of the pencil.
Thoroughly: lift the magnet directly without turning the pencil. Eliminate the paper clip, as well as lay it back in the bottle in the exact very same place. Fill up the bottle half complete with water, then slowly lower the magnet right into the bottle. Be sure not to transform the pencil, so that the string length has actually not altered. The string size, the position of the paper clip are Constants The Variable is the material in between the magnet and the paper clip: air and water.
Does the magnet still attract the paper clip? If so, does it do so from the same range over as it did when the bottle was loaded with air rather than water?
Outcomes and also Final Thought: Jot down the outcome of your experiment. Come to a conclusion regarding whether your hypothesis was appropriate.
Something more: Now test magnetism using seawater, sugar water, or ice water!
