Everything You Need To Know About Neodymium Block Magnets



Permanent solid magnets consisting of an alloy of neodymium, iron, and boron are known as neodymium magnets (also known as “NdFeB,” “Neo,” or “NIB” magnets). They are members of the rare earth block magnets family and have any permanent magnetic characteristics. They are favoured by many consumer, commercial, industrial, and technical applications due to their high magnetic strength and cheap cost.


  • Why do neodymium magnets have such a powerful magnetic field? 

Because of its high saturation magnetisation and resistance to demagnetisation, neodymium magnets are called strong. Strong neodymium magnets are more expensive than ceramic magnets, but they pack a tremendous punch! One of the most significant advantages is using a smaller NdFeB magnet to get the same result as a bigger, less costly magnet.

  • What is the lifespan of neodymium magnets? 

Suppose their physical characteristics stay unchanged and they are not brought in contact with demagnetising forces. In that case, neodymium magnets will likely lose less than 1% of their flux density during ten years (such as high temperatures, opposing magnetic fields, radiation, etc.).

Neodymium magnets are less prone to cracking and chipping and are less expensive than rare earth block magnets such as samarium cobalt (“SmCo”). They are, however, more temperature-sensitive. Because its magnetic characteristics are incredibly stable at higher temperatures, SmCo may be a superior option for applications where this is important.

  • What are some of the most frequent neodymium magnet applications? 

Neodymium magnets are commonly found in audio equipment (microphones, headphones, and loudspeakers), hard disc drives, pumps, bearings, MRI scanners, electric vehicles, wind generators, high-performance motors, actuators, magnetic therapy, anti-lock braking systems, levitation devices, door latches, model making, arts & crafts, home improvement (DIY-fixing furniture, hanging pictures, and more), POP displays, and more.

  • When it comes to neodymium magnets, what are the optimum temperatures to use? 

Without careful magnetic circuit design, these magnets should not be used at temperatures over 130° C (240° F).

  • Is it necessary to treat neodymium magnets? 

In humid circumstances, magnets that are not painted by a surface coating (such as plating) may rust.

  • What are the most popular techniques for putting neodymium magnets together? 

“Super glues,” such as Loctite 325, are often used to combine neodymium magnets into goods. For the most remarkable results, make sure the bonding surfaces are clean and dry.

  • What does permanent magnet mean in Physics? 

The bulk of magnetic materials accessible today are permanent magnets. Unlike electromagnets, permanent magnets are ferromagnetic materials with magnetic fields that do not switch on and off. Permanent magnets, including neodymium, alnico, ceramic (ferrite), and samarium cobalt, are available in a broad range of forms, sizes, and grades.

  • What is the definition of a rare-earth magnet? 

Rare-earth magnets are the most powerful permanent magnets available today, producing magnetic fields that are considerably stronger than ceramic (ferrite) or alnico magnets. Rare-earth magnets come in two varieties: neodymium and samarium cobalt.

  • What criteria are used to evaluate magnets? 

The maximum energy, residual product induction, and coercive force of magnets are considered while rating them. 

  • What does it imply to have “approximate pull info”? 

The estimated pull information provided is for informational purposes only. These figures are based on the assumptions that the magnet will be connected to a 1/2″ thick mild steel plate that is level and ground. Coatings, corrosion, uneven surfaces, and some climatic conditions may decrease the draw force considerably. Please ensure that the natural pull is tested in your application.

What is the Average Cost of Solar Panels and Home Installation?



According to the U.S Energy Information Administration, the average American used 10,649 kWh in 2019.

Depending on the state, that would amount to an average of $200 a month in utility bills. That’s why many people are looking into the cost of solar panels.

The average cost of solar panels has seen a decrease in price due to different factors. Now is the time to make the transition to a more cost-effective energy system. Let’s take a look at the factors that influence the cost of solar panels!

Electricity Needs

First of all, you must consider how much electricity you want them to generate. The average cost per watt is between $2.51 and $3.31. If you need solar panels that produce 5 kW (1 kW is equal to 1,000 watts), you can expect to pay an average of $11,000.

Type of Solar Panels

Not all solar panels are the same. There are different factors you must consider when thinking about the average cost of solar panels. The cost of one solar panel can be as low as $5,000, but at the same time, some larger ones can cost up to $40,000.

It comes down to what material you choose for your solar panels. Monocrystalline is a lot cheaper but not the most efficient. In comparison, polycrystalline is very efficient and considered the best material for solar panels, but it’s expensive to install.

Your Home

The size of your home also factors into the cost of solar panels. As you can imagine, a bigger house will need more panels than a smaller one. The good news is that most homes only need 10 to 30 panels to supply all of their energy needs.

Average Cost of Solar Panels 

Once you figure out the average cost of solar panels, you’ll also need to factor in how much the installation will be. Most reputable solar panel companies, like Blue Raven Solar, will explain in detail the cost of the installation as there are many steps involved.

Let’s take a look at a few things that influence the final installation cost:

  • Permits
  • Design
  • Size of home
  • Number of panels

The company will need to design a solar panel system specific to your home’s layout and energy needs. Additionally, you’ll need specific permits from your state to be able to start the installation. The amount you must pay for each permit may vary from state to state.

Switch to a More Efficient Energy Supply

The initial cost of solar panels may be expensive, but it’ll save you thousands of dollars in the long run. On top of the fact that you’ll be saving lots of money, you can also feel happy that you’re investing in a cleaner future for the environment. Don’t wait any longer, and contact your nearest solar panel company to start saving money.
