You can do an experiment in which you check whether gravitional fields influence the shape of a magnetical field. ❋ Unknown (2010)

In the monument of King Childerick the iron relicks were found all rusty and crumbling into pieces; but our little iron pins, which fastened the ivory works, held well together, and lost not their magnetical quality, though wanting a tenacious moisture for the firmer union of parts; although it be hardly drawn into fusion, yet that metal soon submitteth unto rust and dissolution. ❋ Unknown (2007)
Euripes, and a great rock of loadstones, which may cause the needle in the compass still to bend that way, and what should be the true cause of the variation of the compass, [2998] is it a magnetical rock, or the pole-star, as Cardan will; or some other star in the bear, as ❋ Unknown (2007)
And though some condemn their skill and magnetical cures as tending to magical superstition, witchery, charms, &c., yet they admire, stiffly vindicate nevertheless, and infinitely prefer them. ❋ Unknown (2007)
Polus 'lies, correct those errors in navigation, reform cosmographical charts, and rectify longitudes, if it were possible; not by the compass, as some dream, with Mark Ridley in his treatise of magnetical bodies, cap. ❋ Unknown (2007)
“Iron is susceptible of magnetical impressions,” is of co-existence. ❋ Unknown (2007)
Hence the lieutenant concluded, that it had been influenced by iron ore, or by some other magnetical matter contained under the surface of the earth. ❋ Unknown (2003)
The machine generates electrical power in the stator coils by a rotating magnetical field which is generally produced by a DC magnet. ❋ Unknown (1992)

Dr. Nash suggests the poet may have had in view "a conceit," which is in Brown's "Vulgar Errors," viz., that the body of man is magnetical, and being placed in a boat will never rest till the head respecteth the north. ❋ George Hart (N/A)
The result of Captain Cook's observation must therefore be attributed to some other cause than, as he supposed, to a magnetical power in the hills of this promontory. ❋ Phillip Parker King (N/A)
_Azimuth-Compass_ is an instrument employed for ascertaining the sun's magnetical azimuth. ❋ Various (N/A)
The second may be yet more subtle, and consist of those exceedingly minute atoms, the magnetical effluvia of the earth, with other innumerable particles sent out from the bodies of the celestial luminaries, and causing, by their influence, the idea of light in us. ❋ Unknown (1904)
Being satisfied with the general efficiency of the system arranged by Mr Brooke for our photographic records (of magnetical observations) I wrote to the Admiralty in his favour, and on Aug. 25th the Admiralty ordered the payment of L500 to him. ❋ Airy, George Biddell, Sir (1896)
As regards the reduction of the magnetical results since 1863: In the study of the forms of the individual curves; their relations to the hour, the month, the year; their connection with solar or meteorological facts; the conjectural physico-mechanical causes by which they are produced; there is much to occupy the mind. ❋ Airy, George Biddell, Sir (1896)
Reference is made to the increase of facilities for making magnetical and meteorological observations. ❋ Airy, George Biddell, Sir (1896)
As regards the Magnetical Observations: 'The Visitors at their last Meeting, expressed a wish that some attempt should be made to proceed further in the reduction or digest of the magnetical results, if any satisfactory plan could be devised. ❋ Airy, George Biddell, Sir (1896)
And I personally am most unwilling to recede from the existing course of magnetical and meteorological observations .... ❋ Airy, George Biddell, Sir (1896)
