The term air core coil describes an inductor that does not use a made of a ferromagnetic material. The term refers to coils wound on plastic, ceramic, or other nonmagnetic forms, as well as those that have only air inside the windings. Air core coils have lower inductance than ferromagnetic core coils, but are often used at high frequencies because they are free from energy losses called that occur in. [pdf]

[FAQS about Electrochemical energy storage devices and key materials analysis questions]
The hazards posed by a capacitor are usually determined by the amount of energy stored, which can cause electrical burns or heart . Factors such as voltage and chassis material are of secondary consideration, which are more related to how easily a shock can be initiated rather than how much damage can occur. Although they usually do not leave a burn, shocks as low as one joule have been reported to caus. [pdf]
