Which Is Stronger N35 or N52 Magnet?

When shopping for strong neodymium magnets, you’ve probably come across the terms “n35” and “n52.” But what do these codes actually mean? And how do they compare in strength?

As a professional neodymium magnet manufacturer, we’ll break down the key differences between n35 and n52 magnets in this comprehensive guide. You’ll learn about their magnetic properties, prices, applications, and more.

By the end, you’ll know exactly how these two magnet grades stack up and be able to select the right one for your project. Let’s dive in!

Understanding Neodymium Magnet Grades

Both n35 and n52 refer to grades of neodymium magnets (aka NdFeB or rare earth magnets).

The “N” stands for the rare earth element neodymium, which enables these permanent magnets to be incredibly strong for their size.

The number after the “N” refers to the Maximum Energy Product (BHmax), measured in MegaGauss Oersteds (MGOe). This represents how much magnetic energy the magnet material can hold.

Simply put:

• Higher numbers = a stronger magnet grade.
• While lower numbers indicate a weaker grade.

For reference, here’s a chart of common neodymium magnet grades and their properties:

Which Is Stronger N35 or N52 Magnet

As you can see, n52 is the highest grade available for commercial neodymium magnets today. With a BHmax of 52 MGOe, it’s over 50% more powerful than n35 (33-35 MGOe).

Now let’s explore exactly why n52 magnets are so much stronger.

Key Differences Between n35 and n52 Magnets

There are several key variables that differ between n35 and n52 magnets, which ultimately determine their relative strength.

1. Magnetic Flux Density

Magnetic Flux Density (Br) indicates how much magnetic field lines a magnet can generate per unit area. It’s measured in Gauss or Tesla.

N52 has a higher Br rating than n35 – around 14.8 kGs versus 11.8-12.5 kGs. So all else being equal, an n52 will induce a stronger magnetic field.

2. Intrinsic Coercivity

Intrinsic Coercivity (Hci) measures a magnet’s ability to withstand external demagnetizing forces without becoming demagnetized itself. It’s measured in Oersted or kA/m units.

Again, n52 wins here with a higher Hci of ≥12 kOe versus ≥9 kOe for n35. So n52 magnets can better resist accidental demagnetization.

3. Magnetic Energy Density

As explained earlier, the Maximum Energy Product (BHmax) is the definitive indicator of a magnet grade’s power.

And with a BHmax up to 52 MGOe, n52 magnets can store over 49% more magnetic energy per volume than n35 magnets (max 37 MGOe).

This directly translates into lifted force, torque strength, and magnetic field density.

4. Temperature Resistance

Temperature Rating indicates the max operating temp a magnet can handle before losing magnetism. This depends on grade and size.

For most n35 magnets it’s 80°C (176°F). While n52 magnets have a lower temp rating around 60°C (140°F) on average.

So n35 has better heat resistance overall, though specialty grades (like n48H) can go even higher.

Cost: N52 Magnets Are More Expensive

Given their top-class performance, it comes as no surprise that n52 magnets demand a premium price over lower grades like n35. Exactly how much more depends on size, shape, coatings etc.

But in general, expect to pay ~30-60% more for n52 over n35. Very worth it for the huge boost in lifting strength. But overkill if you just need a basic holding magnet.

N35 strikes a nice balance of cost and power, suitable for the widest range of applications. It’s the most popular grade overall.

Applications: When To Use Each Grade

With key strengths and weaknesses in mind, let’s discuss ideal usage cases for n35 versus n52 neodymium magnets:

N35 Magnets

• General-purpose holding/mounting – the best bang for buck
• Crafty DIY projects like magnetic slime or sculptures
• Science experiments/demonstrations – very affordable
• Learning about magnets – college, high school, elementary

N52 Magnets

• High-torque motors/generators – maximize power density
• Industrial lifting – cranes, separators, holding fixtures
• Precise experiments requiring very strong, stable fields
• High-end speaker/headphone design – compact drivers
• Research & development – always stay future-proof

So in summary:

• N35 = general purpose, crafts, basic experiments
• N52 = advanced motors and tech, industrial, R&D

Both play vital roles across many fields of work and study!

Strength Comparison: N52 Over 50% Stronger!

Given similar shapes and dimensions, n52 magnets are over 50% more powerful than n35 in terms of lifting force, torque rating, and magnetic field density.

You can visually see the difference using a simple trick: dropping the magnets onto a thick steel plate from 4-5 inch height.

The n52 magnet will take significantly longer to fall due to its greater attractive force against the plate. Clearly, the n52 has much stronger binding with the ferromagnetic steel!

While the exact % increase varies across sizes, n52 consistently crushes n35 and even higher grades in raw power.

Conclusion: When To Use N52 Over N35

So should you use n35 or n52 magnets for your application?

It mainly comes down to balancing strength needs and budget.

For cost-sensitive uses like household/hobby projects, n35 offers plenty of magnetic power at the best value.

But for professional or high-performance systems, the sheer strength of n52 is critical – and well worth the added expense.

The range of grades and options lets you tailor the ideal neodymium magnet to your exact requirements.

N35 vs N52 Magnet: Which Is Stronger

In summary, between n35 and n52 magnets:

• N52 is over 50% more powerful in terms of magnetic field density and lifting/torque strength
• N52 has a higher resistance to demagnetization
• N35 is more heat-resistant and cheaper per magnet
• N52 suits high-performance motors, industrial applications
• N35 works well for household projects, experiments, general use

So while n35 magnets boast decent power for the size, n52s are overwhelmingly stronger in direct head-to-head comparison.
