Answer:
1.By simply wrapping wire that has an electrical current running through it around a nail, you can make an electromagnet. When the electric current moves through a wire, it makes a magnetic field. ... There is another way that uses electricity to make a temporary magnet, called an electromagnet.
2.You will change two variables to make different electromagnets: the number of wire coils around the nail (10 or 20) and the number of D cell batteries (1 or 2).
3.1. brass cap, 2. plastic seal, 3. expansion space, 4. porous cardboard, 5. zinc can, 6. carbon rod, 7. chemical mixture.
4.A 2d nail is 1 inch long, for example, while a 16d nail is 3 1/2 inches long. Each higher number in the penny system represents a 1/4-inch length increase, up to a 12d nail (3 1/4 inches long).
