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. decrease the size of the gong and the number of coils around the electromagnet B. increase the current produced by the battery and the number of coils around the electromagnet C. increase the length of the arm supporting the hammer and use a heavier hammer D. decrease the size of the gong and use a larger hammer

Respuesta :

Answer:

Increase the current and coils around the electromagnet to make the bell ring.

Explanation:

      Denver can increase the chances of making the bell ring by increasing the current produced by the battery and the number of coils around the electromagnet. This will strengthen the magnetic field generated by the electromagnet, pulling the hammer with more force toward the gong, causing it to ring. Decreasing the size of the gong and the number of coils around the electromagnet will weaken the magnetic field, making it harder for the hammer to reach the gong.

        Increasing the length of the arm supporting the hammer and using a heavier hammer will not necessarily increase the force with which the hammer strikes the gong.
