PeakForce Tapping in magnetic force microscopy offers superior spatial resolution and sensitivity, enabling precise mapping ...

Magnetism is due to the magnetic fields around magnets. The fields can be investigated by looking at the effects of the forces they exert on other magnets and magnetic materials. Electromagnets ...

This heat drives convection cells within the liquid core, which keeps the liquid metal moving through the magnetic field. The so-called Coriolis force also plays a role in sustaining the ...

Earth’s trusty magnetic field has been keeping the planet safe for at least 3.7 billion years. There’s a chance it might have ...

Electric currents and magnetic fields are closely related. If you have one, you often have (or can make) the other. The braking force in the demonstration is due to an eddy current. That's an ...

Astronomers have developed a computer simulation to explore, in unprecedented detail, magnetism and turbulence in the ...

In essence, the magnet will want to rotate to align with the rotating magnetic field, but its mass will mean there is a time delay for the force to act and rotation to occur, which will lag the ...

Microfluidics experiments and simulations show that magnetotactic bacteria are adapted to the geomagnetic field strength for optimal navigation in sediment environments.
