Measurement of temperature rise of cooling water under pressure and in strong electromagnetic fields is accomplished by a transducer using a magnetically shielded thermocouple arrangement. The thermocouple junctions are immersed in oil to isolate them from electric currents in the water.
Distortions around weld areas on sheet-aluminum tanks and other structures are removed with a portable electromagnetic hammer. The hammer incorporates a coil that generates a controlled high-energy pulsed magnetic field over localized areas on the metal surface.
Performance and applications of electrothermal and hybrid electrothermal-electromagnetic space propulsion
Investigations in astronomy, solid state physics, optical masers, atomic physics, and radioactive atoms for electromagnetic applications
Cryogenically cooled superconducting electromagnet design, construction and testing
Transient resonant response of inhomogeneously broadened nuclear spin system to pulsed electromagnetic field represented as series of Bessel functions modulated by time-varying coefficients
A bifilar winding around the magnetic core of electromagnetic devices suppresses high transient voltages. The winding is alternately spaced vertically and radially from the core to achieve a high coefficient of coupling.
Nondestructive electromagnetic method detects the extent of gold/nickel braze alloy flow in an engine injector sleeve-to-post joint. Voltage is induced in an inductor coil, along with a magnetically permeable material. The effects of altering the quantity of braze alloy present can then be measured.

Electromagnetically driven confined viscous vortex flow with high positive radial Reynolds numbers, solving energy equation for temperature distribution
Electromagnetic device accurately indicates the responses of various sensors in high performance flight research aircraft to conditions encountered in flight. The device responds to sensor inputs to move a slideable armature along an indicator scale by the force of currents induced in the armature winding.
Fast-response coil drive circuit, for electromagnetic torque motors, reduces the inductive coil time constant with a minimum of circuit sophistication. The low-cost modulator servoamplifier is used with a compatible preamplifier stage which provides the servo-loop function of summing, adjustable gain and compensation.
