Dear Professor,

Clarification on Physics and Astrophysics

My Understanding;

Question 1.

Will the magnetised earth cause any (gravitational) pull on other equipment or planets as they also would be magnetised.?

Principally, a coil wound as given below generates the poles. Electromagnetic waves are the full range of electromagnetic radiation.  The electromagnetic spectrum and the earth’s rotation generate the earth’s current flow and this phenomenon is addressed as “GEODYNAMO”. The Earth's magnetic field produced is due to the internal current flow. The Pole formation is due to the current flow, as given below. The magnetic poles are the current geographic South pole and vice versa. The poles generated are thus due to the internal current flow.

Earth's core and the geodynamo

The Earth's magnetic field is believed to be generated by electric currents in the conductive iron alloys of its core, created by convection currents due to heat escaping from the core.

The Earth and most of the planets in the Solar System, as well as the Sun and other stars, all generate magnetic fields through the motion of electrically conducting fluids. The Earth's field originates in its core. This is a region of iron alloys extending to about 3400 km (the radius of the Earth is 6370 km). It is divided into a solid inner core, with a radius of 1220 km, and a liquid outer core. The motion of the liquid in the outer core is driven by heat flow from the inner core, which is about 6,000 K (5,730 °C; 10,340 °F), to the core-mantle boundary, which is about 3,800 K (3,530 °C; 6,380 °F). The heat is generated by potential energy released by heavier materials sinking toward the core (planetary differentiation, the iron catastrophe) as well as the decay of radioactive elements in the interior. The pattern of flow is organized by the rotation of the Earth and the presence of the solid inner core.

The mechanism by which the Earth generates a magnetic field is known as a geodynamo. The magnetic field is generated by a feedback loop: current loops generate magnetic fields (Ampère's circuital law); a changing magnetic field generates an electric field (Faraday's law); and the electric and magnetic fields exert a force on the charges that are flowing in currents (the Lorentz force). These effects can be combined in a partial differential equation for the magnetic field called the magnetic induction equation.

From the explanation of the quotes, we can infer that the earth is magnetised. It is hoped that the magnetic field interfere with electronic instruments.

Question 2

My view and understanding is that gravitation is true, by planets on other planets. I believe and trust that the universal laws of gravitation by Newton are according to the formula and that gravitation is true and acceptable.;

Earth’s orbital velocity may not be constant at 107,200 km/h; 66,620 mph. Can we presume that the Earth is not in an inertial frame of reference to be at 107,200 km/hr because the Earth is subjected to the gravitational pull of other planets? At every position in the orbit, the planet may be subjected to varying forces due to gravitational pull by other planets. Solar System live.

Question 3

The event caused by BIG BANG made the planets disperse and form a rotational path due to the centrifugal and centripetal forces. It could be assumed that the solar system is formed due to the gravitational pull. The SUN is the most unstable and the elements in the sun are in constant decay which therefore is termed radioactive. The rotation may have been a result of the big bang and stabilised due to the forces mentioned.

Even the velocity of light is due to the mathematical deduction using the Maxwell Equations, not by measurements.

Thank you, Sir,
