This isusually the stronger, and, if the interruptions are sufficiently rapid, domi-nates the reversed current. The ends of the secondary coil are attachedto the electrodes. The strength of the current is altered by moving theinner coil away from the secondary coil. This is spoken of as the dis-tance between the coils, and is measured in inches or centimetres. It ismanifest that this method for measuring is not absolute, but its valuemust be determined for each particular machine. This can only be doneby the physiological test—that is, measuring the force required to producecontractions in some muscles and then comparing it with the known value Fig. 56. Fig.
