Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth.

External magnetic fields have been used to vertically align ensembles of silicon microwires coated with ferromagnetic nickel films. X-ray diffraction and image analysis techniques were used to ...

When summer comes knocking hard, an air cooler is like a part of your everyday life. It’s the cost-effective version of air conditioning, cooling you down without breaking the bank on your electricity ...

However, when a rotating magnetic field is introduced, the rolling flow competes with and can eventually overpower the spontaneous propulsion. The researchers found that at 20 Hz, the droplet ...

In an induction motor, the current in the stator windings generates a rotating magnetic field, which induces current in the rotor and causes it to spin.

Magnetoelectric (ME) sensors have a significant potential for detection of weak magnetic fields if the mechanical resonance is utilized. Generally, magnetic and electric modulations can be employed ...

With the rapid development of smart grids, abundant online monitoring sensors are installed at critical nodes of medium and low voltage power lines. To ensure reliable operation of these monitoring ...

Most of these magnetic fields have a plausible origin story. For example, the swirling dynamo of molten iron and nickel inside Earth generates our planet's field.
