Abstract

207,680. Eastern Telegraph Co., Ltd., and Davies, B. Oct. 27, 1922. Magnetic measurements. - A fluxmeter for measuring the field strength of magnets for recorders, relays, &c. comprises a moving coil 1 through which a predetermined current is passed and which is placed in the field to be measured with its magnetic axis at right-angles thereto. The spindle 2 of the coil 1 carries a pointer 11, which is brought back to its zero position by rotation of a torsion head 8 connected to the spindle 2 through a control spring 6. A pointer 9 indicates the angle of rotation of the torsion head 8, which is proportional to the field strength, and may be calibrated directly. A fixed resistance is connected in parallel with the coil 1 for standardization, and a variable series resistance is provided for adjustment of the current. The coil 1 may be rectangular as shown, or of circular or other shape, and may have an iron core O or not.
