POLE FILM MAGNET
Pole Film Magnet is a micro - encapsulated film which enables the user to view a static magnetic field such as commonly emitted by permanent magnets or dc electromagnets.
The highly flexible film easily conforms to magnetic surfaces with any degree of convexity or concavity.
It is used across the globe for quality control, product demonstration, reverse engineering, authentication and educational purposes.
STANDARD COLOR : GREEN
STANDARD THICKNESS : 0.006 INCHES;
Pole tester is shaped like a pen and performs the measurement with a probe in its tip. The sensor position is indicated by a black mark that helps to determine a magnet's neutral zone with precision. The LED changeover from green to red light indicates the south-to-north pole transition.
This hand - held instrument provides for the accurate, quick and convenient measurement of DC magnetic fields.
Standard transverse probe is used to measure magnetic polarity and gauss.
These are typically used to magnetize alnico. Connects to standard 120 VAC outlet. Place magnet or assembly between poles and depress switch for one second.
The following magnetizing forces are recommended -
Alnico 1,2,3 - 4000 Amp / turns / inch
Alnico 5,6 - 6000 Amp / turns / inch
Alnico 8,9 - 10,000 Amp / turns / inch
Ceramic 20,000 Amp / turns / inch
SmCo and NdFeb require capacitor discharge unit.
