The Model 670 IRM (Impulse Remanent Magnetizer) is an easy-to-use tool for magnetizing geophysical cores over a wide range of fields. It operates by charging capacitors with a low current, then discharging the capacitors through a long solenoid to generate a pulsed magnetic field.Read More
The manual controls consist of a power on/off switch, a thumbwheel switch for dialing in the desired field, and a cycle start button. An LED display tracks the building of voltage on the capacitors. When the charge reaches the desired value, the instrument generates the pulsed field automatically.
