We report on calculations concerning the optimization of solenoid coils. The task was to find the best radial current density distribution producing the highest possible field in the center. Constraints consisted of a finite mechanical strength of the coil and an upper limit for the current density...

In this case, the axial component of the magnetic field is measured, rather than the radial component. The drawback of the Hall transducer-based methods is the mapping of the whole solenoid aperture, generally performed with moving stages through sturdy mechanics. When a magnet is in operation,...
Preferably the pulsed field is capacitor-generated via a solenoid and the rate of change of the magnetic field strength is produced by holding the waveform constant and altering the pulse duration, for example by providing taps on the solenoid together with an inductor and a balancing resistor, ...
By means of an electromagnetic coupling, the disc is connected to a flywheel (7). By switching the coupling magnets in synchronism with the solenoids the energy from the solenoids is converted into rotating kinetic energy in the fly-wheel. The power output is from the flywheel shaft. The ...
Assuming a reasonable working stress of 100 MPa, the virial theorem gives for a magnet with steel structure the value of stored energy per unit mass (mass specific energy) of 12.5 kJ/kg (3.5 Wh/kg). The CMS (Compact Muon Solenoid) [7] magnet of the LHC collider almost reaches this ...

coworkers initially predicted that a carbon solenoid with Riemann surfaces and small diameter can behave as a quantum conductor when a voltage is applied, resulting in a large magnetic field near the center and bringing about excellent inductance25....
Some superconducting devices like Superconducting Magnetic Energy Storage (SMES) need a small external stray field and sometimes a constant internal field (MRI). Both problems can be approached using special coil configurations. Basic forms like torus, solenoid, and alternate solenoids with parallel ...
