Question
Denver constructs an electric bell as shown in the diagram below.
He then turns the switch on to test the bell. Denver notices that the hammer moves a bit toward the gong, but does not quite reach the gong. Which of the following should Denver do to best increase the chances of making the bell ring?
A.
increase the current produced by the battery and the number of coils around the electromagnet
B.
decrease the size of the gong and the number of coils around the electromagnet
C.
decrease the size of the gong and use a larger hammer
D.
increase the length of the arm supporting the hammer and use a heavier hammer

To increase the chances of making the bell ring, the best option for Denver would be:
**A. increase the current produced by the battery and the number of coils around the electromagnet.**
Explanation:
Increasing the current will enhance the strength of the electromagnet, allowing it to exert a stronger force on the hammer. Additionally, increasing the number of coils around the electromagnet will also increase the magnetic field strength, which would further improve the performance of the electromagnet. A stronger magnetic force is more likely to move the hammer sufficiently to reach the gong and create a ringing sound.
The other options either do not address the issue effectively or could compromise the setup's ability to generate enough force.
