Custom Permanent Magnets - Dailymag

Permanent magnets are usually made from ferromagnetic materials such as cobalt, nickel, iron, and special alloys. These are also composed of other rare-earth metals including lodestone. Compared to electromagnets, permanent magnets provide more magnetic field without requiring electrical power or an external magnetism source.

Dailymag has years of experience in manufacturing, designing, and engineering a wide range of permanent magnets. We offer custom permanent magnetic assemblies to suit different industries and high-performance applications. Our team provides turnkey solutions to industrial, automotive, semiconductor, aerospace, and more applications.

Working Principle of a Permanent Magnet

Like other magnets, permanent magnets also provide a magnetic field that circulates in different patterns. The strength and size of the magnet are relative to its magnetic field size. To see a permanent magnet magnetic field, dispersing an iron filling can help. You can see that the iron fillings are oriented along the field lines.

Aside from that, permanent magnets have south and north poles. The opposite poles will attract each other while the same poles repel. These magnets are created by exposing the ferromagnetic materials to a high temperature and strong magnetic field. It is cooled and locked in with an aligned domain.

Working Principle of a Permanent Magnet
Strength of a Permanent Magnet

Strength of a Permanent Magnet

The strength of a permanent magnet is determined through the following:

  • Magnetic field strength or remanence
  • Coercivity or demagnetization resistance
  • Pulling force
  • Mega Gauss Oersteds or its maximum energy product value

However, a permanent magnet’s performance can be altered by temperature.

Physical Properties of a Permanent Magnet

Permanent magnets are brittle. It has varying tolerances and dimensions. These magnets are also characterized by different shapes including top hat, miter, arc, disc, square, trapezoids, and more. These are also available in bars, cylinders, or ring shapes.

To improve performance, permanent magnets are often coated with chrome, titanium, gold, rubber, epoxy, stainless steel, PTFE, nickel, and more. Thus, improving its resistance to corrosion and oxidation.

Physical Properties of a Permanent Magnet
Magnetic Orientation

Magnetic Orientation

Permanent magnets have different magnetic direction depending on its physical dimensions such as the following:

  • Axial magnetization
  • Oriented through diameter
  • Radial magnetization
  • Diametrically magnetized
  • Axially oriented through thickness
  • Multi-pole
  • Oriented through length, and more

What is a Permanent Magnet? (Definition)

Permanent magnets generated a magnetic field through their internal structure. The crystals and atoms of a permanent magnet have electrons. Its magnetic field is the result of electron spins and nuclear spins. The strongest magnetic field ranges up to 8000 gausses.

What are the Magnetism and Electromagnetism of a Permanent Magnet?

There are only two poles found in a permanent magnet, the north, and south. Static electricity causes a force to repel the magnets on the same poles and attract each other on opposite poles. Permanent magnets made from ferromagnetic materials are easy to magnetize. Paramagnetic materials are difficult to magnetize while diamagnetic materials repel external magnetic fields.
