Question

Nicki and Austin are working on a school project. For setup A, Nicki coils some copper wire around a bar magnet. For setup B, Austin mounts some coiled copper wire on some paper clips over a round magnet on top of a cup. He connects this to a battery. Which option correctly compares the two setups?

A. setup A: A simple electromagnetic has been made that can spin a copper coil and power a mechanical device; setup B: A simple electric motor has been made that can attract objects that contain iron.

B. setup A: A simple electromagnetic has been made that can attract objects that contain iron; setup B: A simple electric motor has been made that can spin a copper coil and power a mechanical device.

C. setup A: A simple lead-acid battery has been made that can supply electricity to power an electric device; setup B: A simple photovoltaic cell has been made that can harness energy from the Sun.

D. setup A: A simple lead acid battery has been made that can harness energy from the Sun; setup B: A simple photovoltaic cell has been made that can supply electricity to light an electric device.

Answer 1

Nicki's setup creates an electromagnet that can attract iron objects, while Austin's setup configures an electric motor that can spin a copper coil and power a mechanical device. The correct choice of option is B. setup A: A simple electromagnetic has been made that can attract objects that contain iron; setup B: A simple electric motor has been made that can spin a copper coil and power a mechanical device.

Step-by-step explanation:

The correct answer comparing Nicki's setup (Setup A) and Austin's setup (Setup B) is:Setup A: A simple electromagnet has been made that can attract objects that contain iron; Setup B: A simple electric motor has been made that can spin a copper coil and power a mechanical device.

This is because in Setup A, the coiling of copper wire around a bar magnet would create an electromagnet when current is passed through the wire. This electromagnet can then be used to attract ferromagnetic materials such as iron. In Setup B, coiled copper wire mounted over a magnet connected to a battery would create an electric motor. The battery supplies electric current, generating a magnetic field in the coiled wire. The interaction between this magnetic field and the magnet results in rotation, demonstrating the principle of an electric motor.
