Definition: The meter which is used for measuring the
flux of the permanent magnet such type of meter is
known as the flux meter. The fluxmeter is the advanced
form of the ballistic galvanometer which has certain
advantages like the meter has low controlling torque
and heavy electromagnetic damping.

Construction of Flux Meter

The construction of the fluxmeter is shown in the
figure below. The fluxmeter has a coil which is freely
suspended by the help of the spring and the single
silk thread. The coil moves freely between the poles
of the permanent magnet.
