A cell phone could be transmitting a health-risk signal to the outside world if the magnet is too strong, a new study has found.
Researchers at The University of Melbourne have found a cell phone can transmit a signal to nearby objects by detecting a finger-tip movement that is too weak to be detected by a normal smartphone’s sensor.
Key points:The magnet is a type of electrical charge that can be generated by the motion of objects around a mobile phoneThe magnet can cause a signal-absorbing effectThe researchers say they’re looking for new ways to protect mobile devices against magnetismThe researchers believe a magnet in a mobile device can be turned on or off, and could therefore be used to prevent cell phone radiation.
Researchers from The University’s Department of Chemistry and the Department of Materials Science and Engineering and the Melbourne Institute of Technology, published their findings in the journal Nature Communications.
The research team found that an electromagnetic field created by a magnet can affect nearby objects and can also be used as a wireless communication device.
Magnetism is a phenomenon where electromagnetic waves attract and repel each other.
It’s a form of electrical power, which is created by electrical charges on objects.
This electrical power can be used for various purposes, such as transmitting radio waves, or for other purposes.
The researchers found that a magnetic field created in the presence of an electromagnetic charge causes a strong magnetic field to form around a cell.
They also found that it can be applied to objects.
The team found it was possible to turn on or turn off the field, and it could also be applied for wireless communication.
“The magnetisation can also help to detect if the cell phone is in close proximity to other objects,” Professor Daniel Farrar said.
“We’re looking at how the magnetic field affects nearby objects.”
Professor Farrars said the team was looking for ways to make the magnetisation more resistant to magnetism.
He said it was also possible to make it less attractive to other people, for example by applying a magnet to the back of the phone.
“There are some other things that can also have an effect on the magnetism,” he said.
Professor Farars said it could mean that a cell could transmit a magnetisation, for instance if it had a magnet on the back that attracted other people’s hands to it.
“If the magnet was on the phone, the phone might pick up a signal, which would cause it to magnetise the phone,” he explained.
“But if the phone was in close contact with another cell phone, like a child or a dog, the magnet might be more difficult to detect.”
Professor Frarrars also said that some cell phones might also be capable of detecting signals from other objects.
“It’s also possible that other magnetic properties can be transmitted to other devices,” he noted.
“I think it’s possible to do some sort of wireless signal analysis on these phones, for which we’ve developed some technologies.”
Professor Anthony Meehan, who was not involved in the study, said there were other ways to mitigate the magnetising effect.
“These kinds of things that we might be doing in the future, we need to think about how do we minimise the effects that are created by these kinds of devices, which could be used in the field of wireless communications,” he told the ABC.
“They might also give us information on the health status of other people around them, and they might be able to measure the magnetises health.”
Professor Meehans comments are based on the results of a paper published in the Journal of the American Chemical Society by the same group.
