One magnetic surface of these square neodymium block magnets is attached with 3M adhesive. For ease of use, all rectangular (square) neodymium block magnets with adhesive have protective backing strips. You can use square adhesive magnets on almost any non-metallic surface. Adhesive backed neodymium (NdFeB) block (rectangular, square) magnets are optimal solution for many DIY projects. Small sized ones are widely used in package.

This block magnet is custom made for one of our customers for use on security products. As you noticed, they are of N52 grade, which means they are very powerful in pull force.
They can also be applied for magnetic linear motor. Basically there are three types of linear motor:
Cylindrical moving-magnet linear motors;
U-channel linear motors and
Flat linear motors.
The linear motor is often described simply as a rotary motor that has been rolled out flat, and the principles of operation are the same. The forcer (rotor) is made up of coils of wires encapsulated in epoxy, and the track is constructed by placing magnets (usually high power magnets) on steel. The forcer of the motor contains the windings, Hall-effect board, thermistor (to monitor temperature) and the electrical connections. By using a linear encoder, position can be quickly and directly measured at the load for increased accuracy of the load position.

Neodymium iron boron ( NdFeB) is a type of rare earth magnetic material.
NdFeB is the most advanced commercialized permanent magnet material available today.
This material has similar properties as the samarium cobalt except that it is more easily oxidized
and generally doesn't have the same temperature resistance.
However, NdFeB magnets have the highest energy products approaching 52MGOe and are
mechanically stronger than samarium cobalt magents. NdFeB material is more costly by weight than
ceramic or alnico but produces the highest amount of flux per unit of volume or mass amking it very economical for many applicantions. Their high energy products lend themselves to comnpact designs
that result in innovative applications and lower manufacturing costs.
Unprotected NdFeB magnets are subject to corronsion. Surface treatments has ben developed that
allow them to be used in most applications. These treatments include copper, silver,, gold, nickel,
zinc and tin plating and epoxy resin coating.
Beneficial characteristics of NdFeB magnets include their very high energy product, very high
coercive force, and moderate temperature stability. Drawbacks include lower mechanical strength,
and low corrosion resistance when not properly coated or plated.
Magnetic Grades and Temperature:
The Grade of a magent directly refers to the Maximum Energy Product of the material that composes the magnet. It in no way refers to the physical properties of the magnet. Grade is generally used to describe
how "strong" a permanent magnet material is. The energy products is specified in the unites Gauss Oersted.
One MGOe is 1,000,000 Gauss Obersted. A grade forty (N40) would have a Maximum Energy Product of 40 MGOe.The higher the grade the "stronger" the magnet.
Magnetic materials have a wide range of working temperatures. The following chart the various materials and their maximum working temperature. NdFeB material
