... You may see a small reading from the probe even when it is not next to a magnetic field. This is due both to local conditions and variations between data loggers. It is quite usual and can normally be ignored where trends of change and field strength are generally more important than accuracy. Some so ...

A Current Compensated Transformer for Measurement of Large AC
... resistive shunts have a heat loss of up to several kilowatts. Depending on the installation, then require either a large cooling surface shunt or intense forced cooling. Indirect measurement of large currents is done usually measuring current transformers with toroidal core, through which lead to th ...

Magnetic circuits and transformers
... Consider the case of charging up a capacitor C which is connected to very long wires. The charging current is I. From the symmetry it is easy to see that an application of Ampere’s law will produce B fields which go in circles around the wire and whose magnitude is B(r) = μoI/(2πr). But there is no ...
