coil

This turns those coils into an electromagnet and it pulls this armature bar down, moving the needle.

A secondary coil is tuned to the same frequency for resonance, and then boosts that voltage, and there you have it.

He provides tesla coil performances, and he also happens to live directly across the street from my aunt and uncle.

As the voltage in one coil changes, it creates a magnetic field.

This field couples with the other coil, inducing a voltage.

Molecules that are full of potential energy, like a coiled spring, get released to do work in our cells and our bodies more broadly.

While exact details of the story are contested, it's rumored that the pill, however, froze to the freezer coils and broke, foiling the CIA’s plan and granting Castro many more days to satiate his sweet tooth.
