Once the student understands electromagnetism, they decide to take apart their doorbell to see if they can figure out why it’s so quiet. Figure 2 below shows their doorbell’s electromagnet on the left and of a normal (loud) doorbell’s electromagnet on the right.

Question

In one sentence, why do you think the student's doorbell is not as loud as a normal doorbell?

Answer 1

The student's doorbell is likely not as loud as a normal doorbell because its electromagnet may have a weaker magnetic field or insufficient current, resulting in less mechanical movement of the bell mechanism.
