Information

Many Magneto coils have a magnetic core with a piece of iron of a ferromagnetic-like material in the center, which increases the magnetic field. The current through the Magneto coil increases the magnetic field of the ferromagnetized, magnetized material to the magnetic field created by the wire. This is called a ferromagnetic core or iron core coil. A ferromagnetic core can increase the magnetic field and inductance of a Magneto coil by hundreds or thousands of times compared to the coreless case. Ferrite core coils are a variety of coils that have a core made of ferrite, a ferromagnetic ceramic compound. Ferrite coils have low iron losses at high frequencies.

Magneto coil in china
Magneto coils with iron cores forming a closed loop, possibly with some narrow air gaps, are called closed core coils. This geometry minimizes magnetoresistance and produces the strongest magnetic field by providing closed paths for the magnetic field lines. It is usually used in transformers.
Magneto coil manufacturers tell you that a common form of closed core coil is a toroidal core coil, where the core has a toroidal or toroidal shape with a circular or rectangular cross-section. This geometry has minimal leakage magnetic flux and has minimal electromagnetic interference.
Magneto coil manufacturers tell you that coils that have a core that is a straight rod or other non-circular shape are called open-core coils. It has a lower magnetic field and inductance than an enclosed core, but is often used to prevent core saturation.
Magneto coil manufacturers tell you that coils without a ferromagnetic core are called air-core coils. This includes coils wound on plastic or other non-magnetic forms, as well as coils that actually have empty air spaces inside their windings.
