Prolonged exposure to low-level magnetic fields, similar to those emitted by such common household devices as blow dryers, electric blankets and razors, can damage brain cell DNA, according to researchers in the University of Washington's Department of Bioengineering.
Scientists have been able to kill pathogenic bacterial cells of Staphylococcus aureus, a common cause of infections, by pumping them full of magnetosomes and applying magnetic heat.
They have only a moderate magnetic strength, making them unsuitable for applications requiring powerful magnetic fields. Neodymium magnets are relatively more expensive than ceramic magnets. They rust very easily, and extra steps must be taken to protect them from corrosion.
So, there will be no issues at all with the magnets that your phone is likely to come into contact with during everyday use such as those in magnetic cases or cradles or on your purse or handbag. This magnet will damage your phone. 50mm x 50mm x 25mm N52 neodymium magnet. This magnet will not damage your phone.
Magnetism is not felt by the human senses in any obvious way, nor is there any substantial evidence that it is harmful. Yet it does have subtle effects on vision and heart performance.
Neodymium magnets are perfectly safe for humans and animals as long as you handle them with care. Some neodymium magnets are strong enough to cause some serious damage to your fingers and/or hands if they get jammed between a strong magnet and metal or another magnet.
But exactly what types of metals do they attract? Neodymium magnets are known as the strongest magnet material available and have the highest holding strength to these metals. They are called ferromagnetic metals containing mainly iron, nickel and rare earth alloys.
The primary difference being that rare-earth magnets are made from alloys of rare earth elements while other permanent magnets are ferrite or alnico. In contrast, permanent lifting magnets will use the rare earth magnet for it's immediate surface strength and high resistance to demagnetization.
Neodymium magnets are used for:
- Hard disk drives.
- Audio equipment such as microphones, acoustic pick-ups, headphones and loudspeakers.
- Dentures.
- Magnetically coupled pumps.
- Door catches.
- Motors and generators.
- Jewellery.
- Bearings.
HOW ARE NEODYMIUM MAGNETS MADE?
- STEP 1 - THE MIX. Firstly, all the elements to make the chosen grade of magnet are placed into a vacuum induction furnace, heated and melted to form the alloy material.
- STEP 2 - PRESSED.
- STEP 3 - SINTERED.
- STEP 4 - COOLED.
- STEP 5 - A COAT FOR ALL APPLICATIONS.
- STEP 6 - A MAGNET IS BORN.
The Most Powerful Magnet On The Market
- Neodymium magnets, or rare earth magnets, are known to be the most powerful type of permanent magnets available to consumers today.
- Neodymium are one of the more diverse magnets available to consumers, and can be found across various industries.
Any strong magnet will do. Give it a shot and see. Glad to hear it! Refrigerator magnets and the like won't do it.

Household Objects That Use Magnets
- Home Audio Speakers. The speakers in your stereo contain magnets.
- Motorized Household Appliances. Your vacuum cleaner has an electric motor that runs by magnetism.
- Cabinet Door Latch. The doors to many medicine cabinets have a magnetic latch.
- Blocks, Trains and Other Toys.
- Debit and Credit Cards.
Uses of NeodymiumNeodymium is used with iron and boron to create powerful permanent magnets, also called NIB magnets. NIB magnets are used in computers, cell phones, medical equipment, toys, motors, wind turbines and audio systems. Neodymium is used as a crystal (neodymium-doped yttrium aluminum garnet) in lasers.
it is classified as a lanthanide, a rare-earth metal. Is neodymium naturally magnetic? Yes, neodymium is naturally magnetic, because it is a ferromagnetic material, meaning it is an element that can be magnetized. It is used to form permanent magnets but it's also attracted by magnets.
Neodymium is the second most abundant of the rare-earth elements (after cerium) an is almost as abundant as copper. It is found in minerals that include all lanthanide minerals, such as monazite and bastnasite.
Neodymium magnets are so strong because of their high resistance to demagnetisation (coercivity) and their high levels of magnetic saturation allowing them to generate large magnetic fields.
Developed independently in 1984 by General Motors and Sumitomo Special Metals, neodymium magnets are the strongest type of permanent magnet available commercially.
Neodymium magnets (and the nickel plating commonly used on their surface) do conduct electricity. Not as well as, say, copper or aluminum, but it's a conductor.
Magnets repel sharks, studies show, by interfering with their ability to sense electrical fields. A recent study shows that magnets placed on the nets can repel sharks and rays from entering the trap. Shark-repelling magnets may be the perfect antidote to unwanted shark attention while fishing.

Two magnets together will be slightly less than twice as strong as one magnet. When magnets are stuck entirely together (the south pole of one magnet is connected to the north pole of the other magnet) you can add the magnetic fields together.
Sheet magnet is a thin layer of plastic, embedded with millions of magnetized steel particles that act like tiny magnets. The thicker sheet magnet is, the stronger it is.
Very little. Neodymium magnets are the strongest and most permanent magnets known to man. If they are not overheated or physically damaged, neodymium magnets will lose less than 1% of their strength over 10 years - not enough for you to notice unless you have very sensitive measuring equipment.
Unfortunately, however, the current created by moving a magnet over a single wire doesn't provide enough energy quickly enough to actu- ally light the bulb. To light a bulb, or to power anything else, you need to find a way to generate more power, which is the amount of energy produced in a certain time.
The Earth's magnetic field is between 150 and 400 times weaker than a refrigerator magnet.
Place your weak magnet within the magnetic field of a much stronger magnet. Setting it right next to the magnet will produce the best result. The stronger magnet will actually help realign electrons that have spun out of axis since it's creation. Stroke the weak magnet with your larger, stronger magnet.
An electromagnet is a magnet that works with electricity. It can be switched on and off. The coils are nearly always made of copper wire because copper is such an excellent electrical conductor. Electromagnets have many uses.
