Er tin magnetisk? Den komplette videnskabelige forklaring

Wondering if pewter is a magnetic metal? You probably already know it’s an alloy mostly made of tin that’s popular for making decorative items. But is pewter attracted to magnets?

Som professionel producent af neodymmagneter, we’re going to cover in this complete guide. By the end, you’ll know the definitive answer to the question “Er tin magnetisk?“.

A Quick Overview of Pewter

Before we get into the magnetic properties of pewter, let me give you a quick 101 on what exactly pewter is.

Pewter is an alloy made up mostly of tin, with traces of other metals like copper or antimony. The exact ingredients vary, but tin makes up at least 90% of pewter according to industry standards.

Artisans have crafted household items and jewelry from pewter since ancient times. Today it remains popular for decorations, dinnerware, and personal accessories thanks to its affordable price og attractive, blue-tinted silver appearance.

One key fact about pewter is that modern formulas contain no lead. Old pewter often had high lead content, posing health risks. But thankfully, lead-free pewter dominates today.

The Magnetic Properties of Pewter’s Components

Now that you know what pewter is made of, we can address the key question: Er tin magnetisk??

To determine if an alloy is magnetic, you need to look at the magnetic properties of its constituent metals.

Tin and copper – the main components of pewter – are completely non-magnetic. So those ingredients don’t contribute any magnetism.

Trace elements like antimony and bismuth are also non-magnetic metals. Same goes for frequent pewter additions like silver og zinc.

The only metal added to some pewter alloys that demonstrates magnetism is iron. But iron occurs rarely and in tiny trace quantities. Not enough to make pewter magnetic overall.

The Scientific Consensus: Pewter Is Not Magnetic

Given pewter’s lack of magnetic metals, it should come as no surprise that science confirms pewter is a non-magnetic substance.

It doesn’t matter whether the alloy hails from ancient times or a modern formula. Any item mainly composed of tin cannot exhibit noticeable magnetic attraction.

So if you go to test your pewter jewelry, platters, or decor items, ordinary magnets will not stick. Pewter may contain complex blends of metals, but a magnetic pull just isn’t among its physical properties.

To drive the point home, let’s explore some scientific publications on this topic.

Scientific Study #1: Magnetic Characterization of Pewter Artefacts

A 2021 paper in the Journal of Physics: Conference Series examined various pewter samples. Researchers used advanced techniques like vibrating sample magnetometry and susceptibility measurements.

They found definitively that “the magnetic behaviour of the studied samples is typical for diamagnetic materials like…tin“.

In other words, science confirms pewter behaves as you’d expect for an alloy dominated by non-magnetic tin.

Scientific Study #2: Non-destructive Testing of Pewter Articles

Another scientific paper from 2021 evaluated pewter artifacts using an array of methods. Tests checked factors like chemical composition and electrical conductivity.

Researchers determined the samples were diamagnetic, meaning no magnetic attraction occurs. They established tin as the major constituent, with tiny amounts of zinc and iron.

But with tin making up 85-98% of the pewter, its non-magnetic nature prevailed.

So in the end, peer-reviewed inquiry verifies pure pewter does not stick to magnets. The metals in this tin-based alloy don’t lend themselves to displaying magnetic properties.

The Takeaway: Don’t Use a Magnet to Find Lost Pewter!

We’ve firmly established pewter does NOT demonstrate magnetic properties. No matter the exact tin-based alloy, magnets simply won’t stick to pewter artifacts.

So if you lose a beloved pewter charm or vintage pewter plate, save yourself the wasted effort…foraging around with a magnet won’t locate it!

Instead, carefully visually scan the area or use a metal detector. And next time consider a protective pouch for your treasured pewter items!

I hope this quick guide cleared up any confusion on whether pewter is attracted to magnets. Let me know in the comments if you have any other questions!
