Permeability of a magnetic material is a ratio of magnetic induction in the material to the applied magnetizing force. Permeability Check Model PC-500 is used to measure the permeability of feebly magnetic materials such as austenitic stainless steel.

The application of Permeability Check includes :   

• Measures permeability of Stainless Steel   
• Measures permeability of Stainless Steel

The System Consists of:   

• Fluxmeter Model FM-110 ( see Fluxmeter for specifications )   
• Solenoid which generates 500 Oersteds at its center axis is 50mm diameter and 525mm long and can accommodate samples upto 45mm diameter and 200mm long.   
• Constant Current Solenoid Magnet Power Supply for the above mentioned Solenoid with current variable with ten turn control from 0 to 5 Amps., has a stability of 0.1%. Magnetic field generated by the solenoid is displayed by three and half digit panel meter with accuracy of 0.5% and linearity better than 0.5%.
• Demagnetizer for total demagnetizing the sample pieces before starting measurement.

This fixture is used for magnetising and callibration of Moving Coil Meters using AlNiCo 5, AlNiCo 6 magnets.

Additional Information:

• Delivery Time: 4-6 weeks

BLDC Fan multi-pole Magnetising Fixture is used for magnetising BLDC fan magnetic assemby usin Anisotropic Strontium Ferrite magnet upto saturation.

Additional Information:

• Delivery Time: 4-6 weeks

Curie temperature of a magnetic material is the that temperature where the material loses its magnetic property ( there is no magnetic induction in the sample with the application of external magnetizing force ). Curie Temperature Measuring System Model CT-800 is used to measure Curie Temperature of Hard and Soft Magnetic Material.

The application of Measuring System includes :    

• Measures Curie Temperature of Cast Magnets, Ceramic Magnets, Rare Earth Magnets and other permanent magnetic material.    
• Measures Curie Temperature of Soft Ferrites and other soft magnetic materials.

The System Consists of:    

• Null Detector with Pair of Pick Up Coil used to detect magnetization in the sample has a resolution of 1 Kilo Maxwell Turns and drift of less than 0.5%.    
• Electromagnet generating a field of 9000 Gauss in an Air Gap of 15mm.    
• Constant Current Solenoid Magnet Power Supply for the above mentioned Electromagnet current variable by means of coarse and fine controls, has a stability of 0.1%.    
• Furnace with sample top loading facility with temperature range up to 800 C. Fitted with K type thermocouple.    
• PID Temperature Controller cum Indicator for controlling and measuring the temperature of the furnace.    
• Sample Pull Assembly for inserting the sample in the furnace and than pulling out to introduce in magnetic field for Null detection.
