Open the CIPO recordAbstract From the Canadian patent
A method and apparatus for generating and detecting magnetization responses from ferromagnetic ferrimagnetic, paramagnetic, or diamagnetic materials comprises a means for generating an alternating magnetic field. The cycle of the alternating magnetic field includes a first magnetization pulse and a second demagnetization pulse, the energy content of the magnetization pulse and the demagnetization pulse being approximately equal the time, duration of the magnetization pulse being substantially longer than the time period of the magnetization pulse the, demagnetization pulse having a higher magnetic field strength than the magnetization pulse magnetic field strength. The effect of the …

Why it's free to use
- Granted April 9, 1991. A Canadian patent filed before October 1, 1989 lasted 17 years from grant, so its term ended April 9, 2008.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
