#Electric power without transmission lines Hundreds of companies are investing in electricity transferred through magnetic fields. Nikola Tesla, the inventor and rival to Thomas Edison, in the early 1900##s built the Wardenclyffe Tower, a 187-foot-high structure on Long island,
to take the wires out of the power equation by transmitting electricity through magnetic fields. When in the atmosphere, electricity exists as a magnetic field.
The trick is to capture it safely to recharge devices. Today s electric toothbrushes charge wirelessly##as power is transmitted through a magnetic field from the charger to the brush.

The second paper presents designs that show how to build electrical components (such as resistors, inductors, capacitors, sensors and actuators) with self-folding laser-cut materials.
The year-old company uses carbon for both the anode and the cathode portion of the battery and hopes to start producing it later this year.
A battery is made up of an anode on one side and a cathode on the other, with an electrolyte in between.
In a lithium ion battery lithium ions travel from the anode to the cathode through the electrolyte, creating a chemical reaction that allows electrons to be harvested along the way.
While lithium ion batteries are the dominant batteries these days for laptops, cell phones and early electric cars,

The reason for converting energy to microwaves is because it impervious to weather condition and water in the upper atmosphere.
In its broad-beam form, microwaves become safe for birds and insects to fly through. Microwaves also have an efficiency advantage.
Typically power has to be converted twice: first from DC power to microwaves aboard the satellite, then back to DC again on the ground.
In lab conditions, researchers have achieved about 80%efficiency in this kind of power conversion, which is far better than with other forms of power.
The process of trapping sunlight also produces water that can be used to produce potable water and other modern day amenities such as air conditioning.

MRI machines use a magnetic field to get hydrogen atoms in the body spinning in a particular way,
Whereas a conventional microwave radar system uses a moving dish antenna to collect microwaves reflecting off a moving object
the Duke system uses a stationary metamaterial aperture, a strip that guides microwaves to a single sensor.
But here, the source sequentially sends out microwaves of different wavelengths. The returning waves are collected then by the metamaterial aperture.
As microwaves travel down the metamaterial strip, they interact with patterns etched along its surface.
For decades, researchers have suspected that powerful magnetic fields are heating the corona. The Sun's atmosphere is just jam-packed full of magnetic field,
says Cirtain. As the lines of those fields cross and twirl, the theory went, they push and pull the charged gas in the corona, giving it the energy that heats it up.
The problem is that nobody has been able to see the magnetic fields in close up until now. Cirtain and his team have developed the High-resolution Coronal Imager (Hi-C

which can cause plasma to escape the magnetic field containing it in the reactor. They may also be able to use turbulence to disrupt high energy plasma blobs that can rip holes in the reactor.
Magnetic field lines threading through those shells should get compressed and aligned causing some of the material to line up as well.
If the aligned dust contains iron the particles'slight vibrations due to their own heat would produce polarised microwave radiation says Mertsch.
And Jupiter's strong magnetic field means that intense radiation surrounds the moon which makes it difficult for spacecraft to operate.
But sometimes the sun's magnetic field lines can directly link up with Earth's in a process called magnetic reconnection which opens up cracks in the magnetosphere.
and the resulting plasma becomes trapped by magnetic fields in a doughnut-shaped ring around the planet.
Theory had suggested that an extra-strong electric field from the sun can rip plasma away from the plasmasphere during reconnection triggering a plume.
This would make it harder for magnetic field lines to meet up and spark further reconnection. But while ground-based measurements can see a plume forming their resolution isn't good enough to tell for sure
For the first time we were able to monitor the entire cycle of this plasma stretching from the atmosphere to the boundary between Earth's magnetic field

#New material structures bend like microscopic hair MIT engineers have fabricated a new elastic material coated with microscopic hairlike structures that tilt in response to a magnetic field.

Under a magnetic field the liquid only flowed in the direction in which the pillars tilted
