[1][2] It is part of a collection of various types of instruments and experiments on the spacecraft; Waves is oriented towards understanding fields and particles in the Jupiter's magnetosphere.
[1] The major focus of study for Waves is Jupiter's magnetosphere, which if could be seen from Earth would be about twice the size of a full moon.
[8] The search coil is overall a Mu-metal rod 15 cm (6 in) in length with a fine copper wire wound 10,000 times around it.
[9] On June 24, 2016, the Waves instrument recorded Juno passing across Jupiter's magnetic field's bow shock.
[9] Two other instruments help understand the magnetosphere of Jupiter, Jovian Auroral Distributions Experiment (JIRAM) and Magnetometer (MAG).
[10] Another object of study is plasma generated by volcanism on the moon Io and Waves should help understand that phenomenon.
[12] The new results by Chandra, which took the observations during December 2000, showed X-rays coming from the magnetic north pole, but not the aurorae.
[12] Roughly every 45 minutes Jupiter sends out a multi-gigawatt X-ray pulse, and this is synchronized with an emission in radio at 1 to 200 kHz.
[6] The MSC is made of a rod of Mu-metal (a ferromagnetic alloy of nickel and iron) wrapped in fine copper wire.
