Earth’s magnetic field does not simply switch direction like a flipped light switch. It weakens, wanders, and reorganizes ...

When a charge is placed in a magnetic field, the charge experiences a magnetic force wherein the two conditions: 1) the charge is moving relative to the magnetic field 2) the charge’s velocity has a ...

Traditional magnetic separators, however, present a challenge: they generate a magnetic force that is very high near the side of the vessel closest to the magnet and decreases rapidly with distance.

Magnetic force microscopy (MFM) is one of the modes of scanning probe microscopy (SPM). As the name implies, it is used to map magnetic characteristics. MFM investigates the local magnetic fields at ...

For the first time, researchers measured the magnetic pull inside a single bacterium, turning a biological mystery into hard numbers.

A magnetic field will apply a force on a single moving charge, and it will also exert a force on a current on which is a collection of moving charges. The force encountered by a wire of length l ...
