Explanation:

Answer:

Answer:

i. Loudspeaker consists of a permanent magnet with a coil wound

around it.

ii. When current flows through the coil, magnetic field is

generated around the coil.

iii. Due to this magnetic field, the coil moves back and forth.

iv. The frequency and amplitude of the movement of the coil

depends on the variation in the current flowing through the coil.

v. Due to the motion of the coil, the conical screen attached to the

coil also starts moving back and forth.

vi. This back and forth movement of loudspeaker screen gives rise to sound waves in air.
