What Metals Do Magnets Stick To?

Several customers will contact our team of experts to enquire about what materials will our magnets stick to, as magnets will not stick to all metals. Understanding what metals are magnetic and then learning which metals are best for use in your applications is important. So, here at FIRST4MAGNETS, we have decided to show you what magnets will and won’t stick to and explain the reasoning behind these answers. Metals That Attract Magnets Metals that naturally attract magnets are known as ferromagnetic metals; these magnets will firmly stick to these... Read More

Will a magnet damage my phone?

Anyone working with or near magnets will have been made aware of the many health and safety warnings regarding magnets. One warning has always been that you must keep magnets away from computers, credit cards, and even your phone. So, do magnets pose a threat to phones and other modern technology? If so, what threats do they pose and how strong must a magnet be to damage a phone, and what parts of the device would be susceptible to damage? The whole idea can be traced back to older pieces...

How is the strength of a magnet measured?

When considering the ‘strength’ of a magnet there are several key measurements that all contribute to a magnet’s strength in different ways, which can be a little confusing. Also, when trying to determine or measure a magnets strength the answer will be dependent on what is meant by strength be it either the pulling force or magnetic field strength, which are both often referred to as strength. So below we will describe each attribute that contributes to a magnets performance and in turn answer the question how is the strength... Read More

What Material Is Best For Shielding A Magnet?

Shielding a magnet or attempting to block a magnetic field is a subject that several of our customers approach our experts with on a regular basis, so we decided to examine what materials can be used to shield a magnet. Before learning how to shield a magnet it’s important to know that magnetic shielding does not block a magnetic field. No material can stop the lines of flux from travelling from a magnet’s north to its south pole. However, it can be redirected. The simplest example of this would be... Read More

What reduces a magnets performance?

All magnets have a ‘pull’ rating measured in kilograms which relates to how much force acting perpendicular to the magnet to pull the magnet from a steel plate, when in direct contact. The ‘pull’ rating is obtained and calculated under ideal conditions such as a thick enough steel plate which is perfectly flat and clean. As the pull force is slowly steadily increased and is absolutely perpendicular to the magnet face. However, in real world applications, perfect conditions are unlikely and there are six main factors which could affect and... Read More
