Natasha wants to create her own electromagnet that can pick up small pieces of metal like plaper clips or iron fillings. Which list of materials would Natasha need to build her electromagnet?

Question

string, battery, iron nail
battery, iron nail, wire
glass rod, wire, battery
Rubberband, string, battery

Answer 1

To create an electromagnet capable of picking up small pieces of metal, Natasha would need the following materials:

Battery, iron nail, wire

Here's why:

• Battery: Provides the electrical power needed to generate the magnetic field.
• Iron nail: Acts as the core of the electromagnet, enhancing the magnetic field created by the wire.
• Wire: When wrapped around the iron nail and connected to the battery, it creates a magnetic field when current flows through it.

The other options do not include the necessary components for building a functional electromagnet.
