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 ...

Magnetism is a natural force, one that works at a distance. Magnets get their force from magnetic fields created by the atoms within the metal. Magnets are useful for things like turbines we use to ...

How does a magnetic compass work? Well, it’s all down to basic physics and human ingenuity. The key component of a standard baseplate compass is its magnetized needle, which is allowed to spin freely ...

"As the magma cooled to form what is today the world's solid outer crust, magnetism was locked into minerals containing iron, such as magnetite." When you purchase through links on our site, we may ...

An experiment 180 years ago first demonstrated a connection between light and electromagnetism – but the link is deeper than ...

Simulations and satellite data reveal that Earth's magnetic field is more complex than scientists had thought. Scientists ...

Magnetic separation has become increasingly popular in biomedical science and industry. This technology uses magnetic properties of micro/nano-sized particles to separate macromolecules of interest, ...

The Magnetic Shield That Protects Our Climate Earth is surrounded by an immense magnetic field, called the magnetosphere.

Magnetic bead separation is a fast, effective, and clean process that scientists use as an alternative to filtration and centrifugation techniques for separation. Magnetic beads and particles can be ...

Electromagnetism and the weak nuclear force are two distinct fundamental forces. That wasn’t always the case. How many fundamental forces are there in our universe? For particle physicists, answering ...

One of the common modes of scanning probe microscopy (SPM) is Magnetic force microscopy (MFM). As indicated by the name, SPM is used to map magnetic properties. On the nanoscale, MFM probes local ...
