A wild idea has been proposed to generate electric power from Earth’s rotation with the help of magnetic fields. A new ...
Reader Jayant Bhalerao, a college physics instructor, found the story useful in class: “We will share it with our students, so that they can appreciate how ...
They follow the magnetic field lines and, therefore ... but they have a higher density and produce an electric current that surrounds the Earth. Electrons move from the twilight zone to the ...
With today’s data rates of only a few hundred megabytes per second, access to digital information remains relatively slow.
The Analyzer for Cusp Electrons (ACE) is designed to measure electron activity in the region of the northern magnetospheric ...
If these metals have not been turned into a permanent magnet they will still be attracted to a magnet if placed within a magnetic field ... Magnetic fields lines are invisible but they fill ...
A magnetic field is invisible ... different positions in the magnetic field, marking the needle direction each time join the points to show the field lines The needle of a plotting compass ...

While earlier studies identified that quantum entities called excitons are sometimes effectively confined to a single line within the ... The direction of the magnetic field switches to the ...
The strength of the Earth’s magnetic field ranges between 25,000 and 65,000 nano-Tesla (nT) with values of 31-58,000 nT between the equator and 50 degrees latitude.
At a cost not far above £10 ($13.70), this was an impulse purchase driven by curiosity; these devices claim to measure both magnetic and electric fields, but what do they really measure?
