A sound speaker is made of a paper cone attached to an electromagnet. The electromagnet moves back and forth as it interacts with a permanent magnet due to an oscillating current through the electromagnet.

When a sound speaker comes too close to a CRT television, the image on the television becomes distorted. Which of the following best describes why this happens?
A.
The magnetic field from the speaker applies a force on the electrons in the television.
B.
The electric field generated by the speaker increases the number of electrons flowing across the television screen.
C.
The electric field generated by the speaker drains power from the television.
D.
The magnetic field from the speaker destroys the electric field of the television.
