Selection Criteria for Magnetic Stimulating Coils
2
Large, or Small Coils
– circular or figure of 8
Large coils provide a high penetration depth, but are not
very focused. The small coils are more focused, but have a
relatively shallow penetration depth. Thus there is an inverse
relation between penetration depth and focus.The coils
come in many sizes and shapes. The two most commonly
used coils are the circular shaped coil and the butterfly
shaped coil also known as the “figure of 8” coil.
Circular or Parabolic Coils
Butterfly Coils
The Butterfly coils are more focused in comparison with the
circular coils. The two windings are placed side-by-side or
overlapping, enabling the coil to stimulate structures with
focus right under its center. The butterfly coil is useful in
focused stimulation.

facts. More detailed informations at

When applying the circular or parabolic coil, the induced
current in the tissue occurs under the windings. A fairly large
area of body tissue will be stimulated.
The circular or parabolic coil may be positioned
conveniently over many parts of the body, and usually serves
well as a “general purpose coil”.

F coils – Static cooled coils
Static cooled coils. To prevent fast overheating during use
we developed the static cooled F-series of coils. The fluid
absorbes dissipated energy thus enabling more stimulis.

Dynamic cooled coils – Coils with external cooling
When the highest number of stimulations are required dynamic
cooling is required.
The cool unit in combination with the Cool-B65 coil are
the solution if a long duration and high stimulation output is
required.

Placebo coils
MagVenture placebo coils are geometrical identical with the
corresponding normal coils.
Placebo coil are intended for blind testing and have considerable
lower magnetic fields than the normal coils.

Special coils
MagVenture develops special coils for special purposes. Many
coils have been developed. Examples MRi-B88 for use in MR
scanners and the Twin Coil for Magnetic Seizure Therapy
(together with the special MagPro MST stimulator)
Custom designed coils
Besides our standard coils we manufactures custom designed
coils based on specifications from our customers.

General coil features.
All coils are designed for use with Magpro R30, X100, R30
with option, X100 with option and R100.
Coils with build in power control in the coil handle and
trigger button in the handle can also be used with a MagPro
Compact. (coil C-100, C-B60, RT 120-II and MMC-140-II)
Coils without built in power control and trigger button
requires the coil converter when connected to a MagPro
Compact.
Additional accessories
Accessories such as Remote control, MEP monitor, Cable for
external trig, Flexible arm, Flight case for the MagPro, Mag-
Probe, 110/230V power supply for the MagPro etc. are also
supplied by MagVenture. Please see MagVenture on
