1. Description
The inclination instrument is used to measure the
inclination of the earth’s magnetic field, and to
demonstrate the magnetic field produced by a
current-carrying conductor.
The instrument consists of a acrylic base with a pillar
which supports an axially rotatable cradle carrying a
magnetic needle and a scale ring. The magnet
needle is mounted on a bearing consisting of sharp
tips, and is free to rotate in either a horizontal or a
vertical plane according to the direction of its axis.
The sockets on the cradle can be used to pass a
current of up to 5 A through it.
