produced by suitably instrumented telescopes referred to as magnetographs.

applied his technique in electrographs to observe atmospheric electricity, barographs and thermo-hygrographs to monitor the weather, and magnetographs to record.

thermo-hygrographs to monitor the weather, and magnetographs to record the three components of geomagnetic force.

in October 1851, Welsh read a long report on Francis Ronalds"s three magnetographs.

He designed and built self-recording magnetographs which were used at Kew, Eskdalemuir, and other observatories.

around the world, the Kew Observatory had the benefit of self-recording magnetographs, which allowed "the means of obtaining a continuous photographic register.

1886 Self-recording magnetographs placed in new Observatory.

Francis Ronalds and Charles Brooke independently invented magnetographs in 1846 that continuously recorded the magnet"s movements using photography.

Some magnetographs can only measure the component of the magnetic field along.

In 1866, the latter installed a set of self-recording photographic magnetographs, donated by the Royal Society, in a specially constructed underground.

By 1846, photo-magnetographs had been developed by Francis Ronalds and Airy"s associate Charles Brooke.

Adams also compared readings of magnetographs form the observatories of various European cities and compared the “disturbances.
