As for the recovery of Pt-Fe3O4/MCNT, a magnet with a magnetic field strength of 10.5 to 11.0 kOe was put near the Teflon container, driving the magnetic catalyst to be attached to the side with the magnet.
All sound levels were measured inside the magnet with a magnetic electret microphone.
The product GA-MNP were recovered magnetically from the reaction mixture by using a permanent magnet with a surface magnetization of 6,000 G, then washed three times with 100 mL of distilled water, and finally dried in an air oven at 50°C for 24 h and stored in a stoppered bottle for further use.
A new, portable NMR magnet with a tailored magnetic field profile and a complementary radio frequency sensor have been designed and constructed for the purpose of probing in situ the sub-surface porosity of cement based materials in the built environment.
The exposure was performed by a magnet with a fixed magnetic field value of 10 mT ±0.025.
Figure 4d illustrates cell distribution after incubation in the magnetic field generated by a single ring-shaped magnet with a diameter of 7 mm and a thickness of 1 mm.
It generates a magnetic field of 0.87 T in the center of the magnet with a bending power of 0.78 Tm2.
In this study, the simple experiments using a superconducting magnet with a large room-temperature-bore and a micro-scale magnetic column consisting of ferromagnetic wires were carried out to understand the ions separation.
They tested CD34+ cell immunomagnetic labeling and isolation from fresh leukocyte fraction of peripheral blood using the continuous quadrupole magnetic flow sorter (QMS), consisting of a flow channel and a quadrupole magnet with a maximum field intensity of 1.42 T and a mean force field strength of 1.45 × 108 TA/m2.
Because nuclei are charged, there is a magnetic field associated with a spinning nucleus: it behaves like a simple bar magnet with a north and a south pole.
This was accomplished using a new double cosine theta design for the magnetic field which traps most of the return field, and then surrounding the magnet with a special superconducting sheet which traps the remaining return field.
