The Skinny on the Nikon COOLSHOT 50i And something the COOLSHOT PROII STABILIZED doesn't - a magnet mount. (Unfortunately a magnet would interfere with the top model's stabilization technology.)

Lens-position sensors respond to magnetic fields. If you place a magnet near these sensors, the magnetic field will interfere with or temporarily disable the sensors. This can degrade the sensors' accuracy and limit the range of movement available to the lenses.

α-iron, cobalt, and nickel are ferromagnetic, while γ-iron, manganese, and chromium are antiferromagnetic. Lithium gas is magnetic when cooled below 1 kelvin.

With regard to action potentials in brain neurons, the magnetic field resulting from the action potentials created in neurons is one of the tools where the brain of one animal can affect the brain of another. It has been shown that different animals, even humans, have the power to understand the magnetic field.

So in summary, magnets can be used to disable security cameras and mess up the videos, but analog wired cameras are most at risk. IP and wireless cameras have more protection but could still be affected by very strong magnets. Tampering with security cameras is illegal, so magnets should only be used responsibly.

Field you can see that this is the north-south. Direction going like this but if i get another magnet. It very easily overcomes the magnetic field of the earth. And turns towards it. Instead.

Yes, ferrite magnets can incur a permanent loss of magnetization when exposed to temperatures below -40°C. Magnetic products different from standard magnets are even more susceptible to low temperatures.

Low-frequency magnetic fields induce circulating currents within the human body. The strength of these currents depends on the intensity of the outside magnetic field. If sufficiently large, these currents could cause stimulation of nerves and muscles or affect other biological processes.

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.

Block the Security Camera with Your Curtain or Fences Installing fence extensions and hanging curtains over the window are effective methods to physically blind the security cameras from your neighbor. Also, trees and barriers can work. You can plant trees or barriers high enough to block the view of the cameras.

Burglars have also been orchestrating a bizarre attack on security cameras known as “jamming,” This tactic works on cameras receiving wireless signals at a set frequency. Burglars tamper with this by overpowering that set frequency with a more powerful signal at the same frequency.

A magnetic material can be demagnetised using the following methods:

1. Heating the product to above the Curie temperature.
2. Strong vibrations (hammer blows) that can cause a slight reduction in magnetisation due to their own magnetic field.
3. Demagnetisation using an externally applied, alternating decreasing magnetic field.
