This induced magnetic field causes the coil to swing, as the south pole of the coil's magnetic field is attracted to the north pole of the bar magnet field. Once the coil is aligned in this manner it does not move again unless the direction of the current through the coil is reversed by clicking the Flip Battery button.
This action reverses the poles of the magnetic field generated around the coil as the current passes through it, so the coil swings in the opposite direction. To stop the flow of electricity through the coil, click the red Turn Off button. Interactive Tutorials. Subscriber sign in You could not be signed in, please check and try again.

However other researchers held that if the galvanometer were used in conjunction with other measures, such as respiration and blood pressure, the GSR could be a valuable tool for measuring deception.
From the s through the s, the galvanometer or its replacement, one of several psychogalvanometers and their successors, remained standard instruments in psychological laboratories.
The preceding is just a small sample of the early research conducted with this instrument. The galvanometer has been instrumental in psychology research for over a century now. Although it was phased out by more sophisticated measurement devices when electronics came in, the electromagnetic galvanometer ushered in a new era of research blending psychology and biological electrical responses. Thanks for this interesting article. It is helpful for my research on the relationship between the ideas of Jung and Hermann Rorschach.
We have one of these, the one in that picture! Any idea what they are now worth? Thank you for the article, we had no idea what it was!

The mirror galvanometer is one of several instruments used for measuring small amounts of electrical current.
Its use in psychological research led to greater understanding of the physiological underpinnings of emotion.
