When the projectile reaches the launch coil, the magnetic field turns off, resulting in the projectile continuing down the barrel at a high velocity. A portable electromagnetic coil gun calls for a ...

Your wireless charger may be much more inefficient than you realize. It may cost a lot more just to run the simple ...

a coil of wire is moved in a magnetic field. ... the electromagnetic field interacts with the permanent magnet generating a force, which pushes the cone outwards; ...

Magnetizing an object by applying a magnetic field can make it rotate — a phenomenon known as the Einstein–de Haas effect 3. This is because the spins in the constituent material initially ...

The stimulated insulin release can be achieved by a single-coil generated electromagnetic field with an E-shaped iron core at a plane 3–5 mm from the coil surface, which matches the depth of ...
