Not illustrated. 1922 Excerpt: ...METHOD for circuits of non-uniform permeability, great care must be exercised always to include the magnetic whole in the calculations. The value of H computed for a point in the air will not hold for iron placed at that point of the circuit. PROBLEMS ON CHAPTER VII Prob. 29-7. A solenoid for use in connection with flux measurements has a primary (air-core) coil 7 centimeters in diameter and 75 centimeters in length wound with 525 turns of cotton-covered copper wire, which can safely carry 3 amperes. What will be the magnetizing force in gilberts and what flux density will be produced at a point at the center of the axis of the coil if this current is flowing? Prob. 30-7. A Leeds and Northrup wall-type galvanometer Rg = 117 ohms) was found by experiment to have the following calibration as a flux meter: ttN = flux linkages in the galvanometer circuit, d = galvanometer deflection, R = total resistance in the galvanometer circuit. A search coil of 100 turns of No. 36 wire (mean length of turn 1.1 inches) was placed so that it linked all the flux lines of a standard bipolar telephone-receiver magnet. The coil was suddenly moved to the point where it had cut all the flux and the deflection was 30.35 centimeters. What was the flux in maxwells in the receiver magnet? Prob. 31-7. A test solenoid used in connection with a wall galvanometer and made by Robert W. Paul of London has a length of 20 inches. This coil is so wound that the magnetomotive force in gilberts per centimeter is four times the current carried by the solenoid winding. The secondary coil is wound in concentrated form around the solenoid and at the midpoint of the length. What must be the number of turns on the solenoid and what will be the flux linkages of the secondary coil neglecting leakage? Pr...
