Magnetics
This field has allowed the use of efficient electric motors, recording of all types, imaging for biomedical uses and assembly analysis, electronic scanning, it made radar possible through the use of the klystron, TWT amplifier, and magnetron and in the pre-70's the use of core memory. Magnetics continues to improve speaker design, headphone design, display technologies, high power transmitters, microphones, beam accelerators and a world of other items.
