Neodymium Pot magnet with Threaded Stud. Complete with EYEBOLT.
The strong Neodymium magnet is encased in steel which concentrates the magnetic pulling power to the front face.
Please note this pull figure can only be achieved when using the magnet on a flat piece of steel around 25mm thick. When used on thin sections most of the magnetic field will pass through the item and not grip anything. The pull on thin sections will therefore be much less than on thicker items.
These magnets are approximately 10 times stronger than traditional ‘red’ magnets.

But their sizes are usually larger than pot magnets, and, the machining method of their steel housing is different from pot magnets’. Search magnets are used for searching ferrite things in river, sea, or other places.

 Search Magnets Treasure Salvage Magnets Search Magnets Treasure Salvage Magnets Application search for finds of iron at the bottom of rivers and reservoirs in cellars and caves in wells and cellars land in the dumps under bridges and crossings on the site land clearing debris from the iron collecting modern coins from the water (many coin magnets!) rise drowned valuable items (fishing gear, hunting rifles, etc.) Modern Permanent Magnets can attract steel objects or other magnets from large distances and cause trapping injuries. Strong magnets should not be given to children. Many Magnets are brittle and may shatter if they are allowed to ‘jump’ together or they jump onto a steel surface. Strong Magnets may affect or interfere with sensitive electronic instruments. Always keep magnets at least 50mm from such devices. Magnets can destroy information stored on magnetic media such as credit cards, floppy discs and computer hard drives. Keep them at least 20mm away. Analogue watches, televisions and computer monitors can be permanently damaged by placing magnets near them. Users of heart pace makers should avoid being near magnets. Do not use magnets in explosive atmospheres.

AMR vs. GMR Vs. TMR magnetic sensors

AMR vs. GMR Vs. TMR magnetic sensors

Many companies are working hard in the design, development and fabrication of Anisotropic Magneto-Resistance (AMR), Giant Magneto-Resistance (GMR), and Magnetic Tunneling Junction (MTJ) magnetic thin film sensors.

AMR vs. GMR Vs. TMR magnetic sensors

Working with a variety of magnetic materials (see table below) AMS deposition techniques achieve optimal conditions (uniformity, composition control, easy/hard axis orientation). The thickness range of these materials spans from <10Å (1nm) for GMR and MTJ applications to >10µ for magnetic shields and flux-concentrators.

Materials	Magnetic Properties	Application	Deposition Technique	Typical Layer Thk.
NiFe (Permalloy)	Soft	AMR, GMR sensors	Sputtered	10Ǻ – 1000Ǻ
NiFe (Permalloy)	Soft	Shields, Poles	Plated	1µm – 10µm
NiFe (45/55)	Soft, higher moment	Shields, Poles	Plated	1µm-10µm
CoPt	Hard, high coercivity	Permanent magnets	Sputtered	500 Ǻ – 10 µm
Co ternary alloy	Soft, higher moment	Shields, Inductors, Poles	Sputtered	1 µm – 10 µm
IrMn, PtMn	Anti-ferromagnetic	GMR, MTJ sensors	Sputtered	50 – 250 Ǻ

typical AMR transfer curve

We use several different vacuum deposition tools to deposit a variety of magnetic materials, including the GMR / MTJ cluster disposition system seen below. The metrology equipment for the characterization of magnetic materials includes BH loopers, VSM (Vibrating Sample Magnetometer), MFM (Magnetic Force Microscopy) and RMM (Remanent Moment Magnetization).

SMC – Soft Magnetic Composite

SMC – Soft Magnetic Composite

The main material of SMC(Soft Magnetic Composite) is the high purity iron powder, insulated on the surface, pressed with the powder metallurgy tech, heated to be the SMC cores. The ‘new’ of SMC is shown in the ‘low’ high frequency eddy losses, high saturation induction intension, and being easily processed to be the complex 3D structure. In application SMC can make motors small, reducing power consumption, saving wire and easy assembling etc.

SMC – Soft Magnetic Composite

SMC Advantages

SMC(Soft Magnetic Composite) is developed in order to replace traditional silicon steel sheets, it has below advantages compared with silicon steel sheets:

I. Low iron losses while running in high frequency:There is an insulating protective frlm on the surface of every particle of the materials to make high electrical resistivity, so the eddy current losses are reduced to a large extent.

II. Raising material utilization: With PM formed, the material utilization is beyond 95%.

III. Easy pole shifting: Do not need magnetic orientation, also can be designed in 3D structure.

IV. Low heating:As for the low eddy current losses and high efficiency make the low energy consumption, so heating is improved while motors run in high frequency.

V. Precise tolerance: The dimension is completely controlled by module to make the size precise and surface smooth.

VI. Reducing motor cost: SMC cores can be processed in 3D structure to shorten axial size to save wires.

VII. Lower Magnetostrictive coefficient: Obvious reducing motor noise.
