Natasha wants to create her own electromagnet that can pick up small pieces of metal like paper clips or iron fillings. Which list of materials would Natasha need to build her electromagnet?
1string, battery, iron nail
string, battery, iron nail
2battery, iron nail, wire
battery, iron nail, wire
3glass rod, wire, battery
glass rod, wire, battery
4Rubberband, string, battery
Rubberband, string, battery
2battery, iron nail, wire
The correct answer would be 2) battery, iron nail, wire.
To build an electromagnet, Natasha would need a few components:
- Battery: to provide an electrical current
- Iron nail: to act as the core of the electromagnet and attract the metallic objects
- Wire: to create a coil around the nail and carry the electrical current
So, option 2) includes all the necessary materials for constructing an electromagnet.
To build an electromagnet that can pick up small pieces of metal like paper clips or iron fillings, Natasha would need the following materials:
2. battery, iron nail, wire
Explanation: An electromagnet can be created by coiling a wire around an iron nail and passing an electric current through the wire. The iron nail acts as a core material that enhances the magnetic field generated by the electric current. The battery serves as a power source to provide the electric current to the wire. Coiling the wire increases the magnetic field strength, making it capable of picking up small metal objects. The string, rubberband, glass rod, or other materials listed in options 1, 3, and 4 are not necessary for building an electromagnet.
