Explanation:

a

1) Magnet: The magnet provides the fixed magnetic field against which the field from the coil operates. The magnet is typically made from ferrite or powerful neodymium.

(2) Chassis / frame : The moving coil loudspeaker is generally built on a circular frame - occasionally these may also be elliptical

b....The moving coil loudspeaker uses the magnetic effect generated by a flowing current as the basis of its operation. When a current flows in a wire, a magnetic field appears around it. When the wire is wound into a coil, the effect is increased
