The magnetic field surrounding a bar magnet can also be plotted using a compass. A compass aligns itself with the magnetic lines of force at each position. The compass needle rotates a full 360° as it is moved from one pole of the magnet to the other. The movement of the compass pointe...
Electron vortex beams are free-electron waves that carry orbital angular momentum. There has been growing theoretical and experimental interest in the use of electron vortex beams as a tool for the investigation of magnetic materials. However, due to the
Electric control of magnetic vortex dynamics in a reproducible way on an ultrafast time scale is a key element in the quest for efficient spintronic devices with low-energy consumption. To be useful, the control scheme should ideally be swift, be scalabl
Magnetic field is the area around a magnet. The magnetic field is the region around a magnet where the magnetic forces are observable. It is defined by the presence of magnetic force on moving charges, which are experienced as attraction or repulsion. This field can be visually represented by...
Calibration of magnetic force microscopy tips by using nanoscale current-carrying parallel wires Experimental results on the characterization of commercially available magnetic force microscopy (MFM) thin film tips as a function of an external magnetic...

Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron. Learn more abo
Basic to magnetism aremagnetic fieldsand their effects on matter, as, for instance, thedeflectionof moving charges and torques on other magnetic objects. Evidence for the presence of a magnetic field is themagnetic forceon charges moving in that field; theforceis at right angles to both thefi...
Magnets, or the magnetic fields created by moving electric charges, can attract or repel other magnets, and change the motion of other charged particles. A magnetic field exerts a force on particles known as the Lorentz force, according to Georgia State University's HyperPhysics website. The ...
A magnet will only affect ferromagnetic metals, but they also have a faint effect on paramagnetic ones. When you place them near a magnet, the diamagnetic metals express a weak repulsion force. In essence, only ferromagnetic metals have magnetic properties. ...
force on the cells loaded on the microrobot increases as the flow rate increases (details are found in theSupplementary File). This finding also proves that our designed microrobot with NTS is relatively resistant to the shear force of blood flow and prevents cell loss during transportation in ...
