It will likewise react to the artificial wave fronts coming from the induction coil. The coherer in a distant receiving station will react to natural electromagnetic wave fronts from the Sun. The Earth and coherer are both doing the same thing with the same kind of electromagnetic waves. An electromagnetic wave from the Sun disturbs the Earth's magnetic field in the same way that an induction coil used in wireless telegraphy does. Every oscillation sends out a wave, like a stone falling in water. No magnet can be placed near a "current" of electricity, or a static charge without making an oscillation. Could the coherer of the days of old teach us something new? The aurora is known to be electrical, for magnets and compass needles on ships are always affected. The field of the Earth is "tuned" with the Sun's field, as was the coherer in the days of wireless telegraphy and telephony. It is caused by the turbulence set up in the Earth's magnetic field by electromagnetic upheaval on the Sun. The light, although caused by the Sun, does not come direct. It displays many colors, and these flash and glow with rapid variations. In a six-month winter, say at the North Pole of the Earth, the Sun is far south of the equator, and none of its rays can shine on the Earth's northern pole. An aurora is the visible effect of obscure undulations from the Sun, as they come dashing on the Earth with a speed of 186,000 miles per second. The Earth's aurora holds the key to harnessing the Sun's daily pulsation. At other locations, switchboards in telegraph offices were set on fire and sending keys were melted, while electric balls were seen hovering on the telegraph lines in Nebraska. In Milwaukee, the carbons in the electric lamps were lighted, rendered incandescent by currents of electricity flowing on the wires.
The turbulence filled that great quadrilateral from New York to Yankton, Nashville and Winnipeg. In some places telegraphic communication was suspended.
The daily press was burdened with accounts of widespread magnetic disturbance. This was one of the most violent recorded. The most memorable magnetic storm occurred on November 17, 1882. So, radiance traveling at 186,000 miles per second is reaching the Earth in eight minutes and nineteen seconds. When a gas jet is hurled across a spot on the Sun the disturbance reaches the Earth in the same time that light does. Now, if this field becomes disturbed, that is if it becomes stronger or weaker, the needle will move. Suspend a sewing needle by a silk fiber in the Earth's magnetic field and it will come to rest parallel to the field's north and south poles. A freely suspended magnet in a magnetic field will move, and the Earth's surface is surrounded by a magnetic field, that is acted upon by the Sun's magnetic field. This space might be filled with air, wood, stone, glass, or might be a vacuum. A magnetic field is space that surrounds a magnet. Detectors that astronomers use to visualize the universe make use of the entire EM frequency spectrum, but humans, who can naturally detect radiation only in the light spectrum, have invented technologies to identify and harness frequencies from low-energy radio waves, microwaves and infrared waves to high-energy X-rays.Power, which beat and surge against the Earth.
What is radiant energy full#
Atomic decay, because of the weak nuclear force, and violent atomic interactions in star evolution produce the full radiative power spectrum. The faster the packets oscillate, the greater amounts of radiant power they transmit. The sun is the Earth's closest source of EM radiation, distributing a wide range of energy packets, called quanta, oscillating at various frequencies. Water molecules are agitated by radiant power in a microwave. This is done mostly to produce electricity. Municipalities, homes and businesses employ processes to harness power from various sources of radiant energy. Incoming EM energy can be transformed at the target into other forms of usable energy as well.
