Tiny magnetic "flowers" engineered by physicist Anna Palau are redefining how we manipulate magnetic fields. These ...

This magnetic field changes as the current changes ... The induced voltage causes an alternating current to flow. Transformers can only work with alternating current. Input and output voltages ...

a primary potential difference drives an alternating current through the primary coil the primary coil current produces a magnetic field, which changes as the current changes the iron core ...

A flower-shaped structure only a few micrometres in size made of a nickel-iron alloy can concentrate and locally enhance magnetic fields. The size of the effect can be controlled by varying the ...

How a tokamak works: The electric field induced by a transformer drives a current (big red arrows) through the plasma column. This generates a poloidal magnetic field that bends the plasma current ...

The flyback transformer is custom-wound with copper wire to achieve the necessary inductance for plasma generation. Its AC output is rectified to DC using a high-voltage microwave diode, as DC is ...
