1. Explain why Elly and Maggie should use those materials for their
electromagnet.
2. How will they test the strength of their electromagnet?
With the materials they gathered, how will Elly and Maggie increase
the strength of their electromagnet?
3. How will they remove the things which will stick to the
electromagnet?
4. Will they get the same result if they will use the other materials in the
maze? (rope, wooden stick, pebbles). Why?
Answers
Answer:
1.These materials are used to make an electromagnet, that's why we should also use them to make one, not only these materials can make an electromagnet but other stuff.
2. They will have to measure the magnets strength by counting the number of paperclips your electromagnet can lift. They can also increase it by using more coils of wire, the number of dry cells also affects the strength of an electromagnet,more dry cells means more electrons flowing in the electromagnet.
3. You could either turn off the switch if you have or turning the batter around.
4.not because it is not necessary.
Answer:
The correct answer of this question is to create electromagnets, so we should utilise them to create one as well. In addition, these materials can be used to create other things besides electromagnets.
Explanation:
Given - Elly and Maggie should use those materials for their electromagnet.
To Find - Choose the correct option.
1) These materials are used to create electromagnets, so we should utilise them to create one as well. In addition, these materials can be used to create other things besides electromagnets.
2. They must count how many paperclips your electromagnet can lift in order to determine the magnet's strength. The strength of an electromagnet can also be increased by adding more wire coils, as more dry cells result in more electrons flowing through the electromagnet.
3. You could either flip the battery around or, if you have a switch, turn it off.
4. No, it's not essential.
