In what ways did the electromagnetic pickup lead to the guitar becoming a solid-body instrument?

An electric guitar is a guitar that uses one or more pickups to convert the vibration of its strings into electrical signals. The vibration occurs when a guitar player strums, plucks, fingerpicks, slaps or taps the strings. The pickup generally uses electromagnetic induction to create this signal. Instead, solid-body instruments depend on electric pickups and an amplifier.
