Magnets can be used for attracting ferromagnetic materials. Magnetism and electricity are very closely related, and the science behind it, is used very much in technology. Magnets attract or repel other magnets, but are also used to store memory in a computers hard drive and to turn electricity into motion.

Magnets Are Everywhere

• Fridge Magnets. White HOOK-WHT hooks holding up a few aprons on a steel door.
• Magnetic Cabinet Latches. Magnetic cabinet catch.
• Audio Speakers. Audio Speakers.
• Electric motors. An electric motor from a DVD drive.
• More Electronic Devices.
• The Internet.

Magnets can be found in the simplest or most complex devices you use every day. From home appliances such as the refrigerator, microwave oven and electric fan, to your company’s office equipment such as computers and printers….The kitchen is full of magnets

• Microwave magnets.
• Refrigerator doors.
• Spice and knife rack.

Magnets stick to metals that have strong magnetic properties themselves, such as iron and nickel. Metals with weak magnetic properties include aluminum, brass, copper and lead.

The magnetic field created by the fridge magnet aligns the spins of unpaired electrons in metal atoms in the fridge in such a way that the magnet and the fridge door are attracted to each other; this force keeps the magnet stuck to the fridge.

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.

Putting a piece of iron or steel inside the coil makes the magnet strong enough to attract objects. The strength of an electromagnet can be increased by increasing the number of loops of wire around the iron core and by increasing the current or voltage.

Generally speaking, magnets below 3000 Gauss (magnetic field unit) are basically harmless to the human body, while magnets with magnetic field strength above 3000 Gauss are harmful to the human body. Although some magnets are harmful to humans, this negative effect is also negligible.

Studies have examined associations of these cancers with living near power lines, with magnetic fields in the home, and with exposure of parents to high levels of magnetic fields in the workplace. No consistent evidence for an association between any source of non-ionizing EMF and cancer has been found.

Summary: 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.

Laboratory studies suggest that electric and magnetic field exposure may affect heart rate and heart rate variability. Epidemiologic evidence indicates that depressed heart rate variability is associated with reduced survival from coronary heart disease as well as increased risk of developing coronary heart disease.

Magnetic nanoparticles (tiny magnetic particles 1-1000nm in size) are used in many different areas of research. 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.

Researchers have shown that a mild magnetic field can cause the smallest blood vessels in the body to dilate or constrict, thus increasing the blood flow and suppressing inflammation, a critical factor in the healing process.

Researchers saw a long-lasting drop in blood pressure following exposure to high magnetic fields.

The health sector is another field where neodymium magnets are incorporated in medical devices for example in magnetic resonance imaging devices to diagnose and treat chronic pain syndrome, arthritis, wound healing, insomnia, headache, and several other diseases due to their ability to generate a static magnetic field.

Magnet treatment is relatively safe. Some patients may experience dizziness, low energy, palpitation, nausea, and vomiting. Side effects can include a decrease in blood pressure, or local skin areas can become itchy, burning, and painful; however, side effects only happen in a very small percentage of cases.

Studies confirm these treatments are ineffective for arthritis pain. Magnet therapy or wearing copper jewelry may seem attractive for easing your arthritis pain simply and inexpensively. But studies confirm these treatments are ineffective for arthritis pain.

Keep your WD-40 for squeaky hinges, not squeaky joints. The popular spray lubricant promotes itself as having more than 2,000 uses, but according to the company itself, easing arthritis joint pain isn’t one of them, says D’Adamo.

The link between coffee and increased risk of rheumatoid arthritis (RA) and osteoporosis is debatable. Some studies say coffee increases the risk, while others do not. Tips: In general, the best rule of thumb is to drink coffee in moderation – no more than one or two cups of coffee a day.

Scientists have designed a hydrogel loaded with magnetic particles and laboratory-grown neurons. By applying magnetic force, the researchers were able to reduce the pain signaling of the neurons. Share on Pinterest When applied to neurons, a magnetic field can reduce the cells’ pain signals, suggests a new study.

Research studies don’t support the use of static magnets for any form of pain. Electromagnets may help with osteoarthritis but it’s unclear if they can relieve the pain enough to improve quality of life and day-to-day functioning, a 2013 research review concluded.

Magnets are used in science, industry, and everyday life. At home, magnets hold your refrigerator door closed and make your computer speakers work. They are used in nearly all machines that use electric motors, such as vacuum cleaners and electric fans. We owe a lot to magnets!

The maximum energy product of a magnet is measured in Mega Gauss Oersteds (MGOe). This is the primary indicator of a magnets ‘strength’. In general, the higher the maximum energy product value, the greater the magnetic field the magnet will generate in a particular application.
