Messapparatur zur genauen punktweisen bestimmung grossflächiger magnetfelder
1966 Edition, Volume 2, September 1, 1966 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The principle underlying the method of automatic measurement of air gap flux densities is discussed. With this, a search coil is used and the voltage by time area is converted into a sequences of pulses in a voltage frequency transformer. An after-connected counter effects indication of the voltage...
