Question

Яким чином прилетивши на незнайому планету космонавти можуть за допомогою чуттевого гальванометру и мотка дроту визначити чи володие планета магнитного полем ?

Answer 1

Подключить моток проволоки к гальванометру и привести в движение ( колебательное или вращательно) если есть магнитное поле то гальванометр покажет наличие индукционного тока

Answer 2

Determining a Planet's Magnetic Field Using a Sensory Galvanometer and Wire Coil

To determine whether a planet possesses a magnetic field, astronauts can utilize a sensory galvanometer and a wire coil. The process involves inducing an electric current in the wire coil through the planet's magnetic field, which in turn generates a magnetic force that can be detected by the sensory galvanometer.

Sensory Galvanometer: A sensory galvanometer is a device used to detect the presence and strength of an electric current. It typically consists of a coil of wire suspended in a magnetic field, with a pointer attached to the coil. When an electric current flows through the coil, it interacts with the magnetic field, causing the coil to move and the pointer to indicate the presence and strength of the current.

Wire Coil: The wire coil, also known as a solenoid, is a coil of wire wound in the form of a cylinder. When an electric current passes through the wire coil, it generates a magnetic field around the coil. The strength and direction of this magnetic field depend on the current flowing through the coil.

Process of Determination:

1. Setup: The astronauts would set up the sensory galvanometer and the wire coil in a manner that allows them to induce an electric current in the wire coil.

2. Inducing Current: By moving the wire coil through the planet's magnetic field or by altering the magnetic field around the wire coil, an electric current is induced in the wire coil.

3. Detection: The induced electric current in the wire coil generates a magnetic force, which can be detected by the sensory galvanometer. The deflection of the galvanometer's pointer indicates the presence and strength of the magnetic field.

Conclusion:

By observing the deflection of the sensory galvanometer's pointer when the wire coil is exposed to the planet's environment, astronauts can determine whether the planet possesses a magnetic field and gain insights into its strength. This method allows for the assessment of the magnetic properties of a previously unexplored planet.
