Question

Mae is designing an experiment to provide evidence that an electric current can produce a magnetic field. She has decided to generate a magnetic field with an electric current and test if it will attract paper clips. In addition to the wires needed to build a circuit, which of the following objects does Mae need to use?

Answer 1

To design an experiment that generates a magnetic field with an electric current and tests if it can attract paper clips, Mae will need the following objects in addition to the wires needed to build a circuit:

1. Power Source: A battery or power supply to provide the electric current.
2. Electromagnet: This could be a coil of wire wrapped around a ferromagnetic core (like iron) to help create a stronger magnetic field when current flows through it.
3. Paper Clips: To test the magnetic field's ability to attract ferromagnetic materials.
4. Switch (optional): To control the flow of current in the circuit, allowing Mae to easily turn the electromagnet on and off.

These objects will help Mae successfully conduct her experiment and observe the effect of the electric current on the attraction of paper clips.
