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.

Neodymium magnets are the strongest magnets. These are widely used for hard disk drives, dentures, door catches, and more.

SmCo magnets are designed with wide temperature range, corrosion resistance, and excellent temperature coefficients.

AlNiCo magnets are widely used for different applications including electric motors, guitar pick up, microphone, sensors, bearings, aerospace, and more.

Flexible magnets are designed to be used for display advertising, crafts, business cards, vehicle signs, magnetic bookmarks, and more.

Dailymag offers custom rare-earth magnets that are less temperature sensitive, corrosion resistant, and different shapes, sizes, and thickness.
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.


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.


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
Materials for Permanent Magnet Production
Dailymag fabricates permanent magnets using high-quality and licensed materials with premium grades such as the following:
- Rare-Earth materials
- Neodymium
- AlNiCo materials
- Samarium cobalt
- Ceramic or Ferrite materials
Aside from that, we also have Inconel, aluminum, and steel materials stock for permanent magnetic assemblies. You can also request special material.

Structure, Physics, Assemblies, and Applications of a Permanent Magnet

Permanent magnets are structured with different physics such as the following:
- Magnetic Field. It is determined by the magnets’ direction and magnitude.
- Magnetic Moment. It is characterized by the magnet’s magnetic properties.
- Magnetization
- Modeling Magnets. There are two different magnet models including the atomic currents and magnetic poles.
- Polarity. Permanent magnets have two poles including the north and south poles.

Our permanent magnets are designed to suit different applications including:
- Microphones and speakers
- Electric guitars
- Generators and electric motors
- Medical Equipment

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.
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.
