Compasses show the direction of the magnetic field around a current in a wire. Iron filings align with the field lines. Place wire and compasses, if desired, under document camera or on projector. If ...
Place wire and compasses, if desired, under document camera or on projector. If using document camera, place sheet of paper underneath for visibility. If using an overhead projector, focus it on the ...
Our planet’s magnetosphere has seen dramatic shifts across its history—even total reversals—but this recent wrinkle doesn’t ...
In 1845, Michael Faraday discovered what’s known today as the Faraday Effect—which describes how light and electromagnetism ...
The vestibular system, a set of structures in the inner ears that helps with balance, may grant the birds their special ...
Explore the fascinating world of clean energy with this step-by-step DIY magnetic generator build. Learn how everyday items ...
The average Hackaday reader likely knows, at least in the academic sense, what a magnetic field looks like. But as the gelatinous orbs in our skull can perceive only a tiny fraction of the EM spectrum ...
Multiple lines of evidence suggest that pigeons sense magnetic fields by detecting electric currents in their inner ears.
A submillimeter-thick film with magnetic microdomains was used to control a Q-switched laser, increasing its pulse power 1,000 times The "Industry 4.0" concept, first introduced by the German ...
In 1882, the French Naturalist Camille Viguier was among the first to propose the existence of a magnetic sense. His speculation proved correct. Many animals—from bats, to migratory birds and sea ...
