Equipment: A compass, iron filings, a current carrying solenoid and a 40 Amp power supply. What it does: The compass shows the direction of the field lines in and around the solenoid. The iron filings ...

The traditional method for visualizing magnetic fields, which your science teacher probably demonstrated at some point, is to sprinkle some iron filings onto a piece of paper and hold it over a ...

Overview Compasses show the direction of the magnetic field around a solenoid. Iron filings align with the field lines.

A compass does not point directly at the physical location of magnetic north. It is oriented along the Earth's magnetic field lines at its location.

Essentially, a solenoid is a compact electromagnet that can be used as a mechanical or electrical switch. Its main component is a coil of wire that's wound around a cylindrical support known as a ...

Chaotic magnetic field lines may answer the coronal heating problem Scientists show how chaotic magnetic field lines result in stronger current sheets and extreme heating of the sun's corona Date ...

The simplicity of the magnetic compass masks the theory behind its operation to some degree and completely fails to deliver any quantitative data on the Earth’s magnetic field. [tsbrownie]’s ...

An application note from an IEEE Magazine shows that STT-MRAM memories should be able to achieve high densities with simple precautions in normal ambient magnetic fields.

The test also demonstrated that the CSMC could create a magnetic field of 5.7 Tesla, about 100,000 times stronger than Earth’s. It also reached a record for stored energy, reaching 3.7 megajoules.

Unmanned aircraft systems – more popularly known as drones – have emerged as a novel method of inspecting power lines, allowing power utility companies to review the health of their infrastructure ...

The Earth's magnetic field is essential to life as we know it. But it’s something we can never see – or hear, until now. In a recent study released on Oct. 10 by the European Space Agency ...

The search for magnetic monopoles has consumed the field of condensed matter physics for nearly a century. Now an international team of scientists from the U.K. and China have found emergent ...
