Scientists have discovered a way to create and cancel magnetic fields at a distance, and the method involves operating the electric current through a special arrangement of wires to create a magnetic field that appears as if it came from another source, which can be used in real fields, so a magnetic field can be created from outside the body that is concentrated Directly on the tumors, thus you can deliver the drug without a surgical procedure.
According to the US space website, Rosa Match Patel, a physicist at the Istituto Italiano Di Tecnologia Center for Biomolecular Nanotechnology in Italy who led the new research, said: “If you don’t have a maximum magnetic field in an empty space, that means you don’t. You can create a magnetic source field at a distance, without placing an actual magnetic source at the target location.
Despite this, Match Patel and her colleagues thought that they might be able to overcome this problem, and the researchers envisioned a material with negative magnetic permeability1, and the magnetic permeability of a material indicates how much this material increases or decreases in the magnetic field when exposed to that field.
The new method for stimulating magnetic fields that relied on non-existent materials would not be particularly useful, but although this hypothetical negative-permeable material does not exist, physicists can create a kind of temporary “substance” from an electric current that passes through a particular arrangement of wires.
“Ultimately, we do not use any substance,” Patel added. “We use a precise arrangement of streams that can be considered active.”
To create the field from a distance, Patel and her team created a hollow cylinder made of about 20 wires surrounding a long inner wire.When current passes through these wires, it creates a magnetic field that looks as if the long inner wire is already outside the device.
