A broan ceiling fan that uses a magnetic field to move air around a room could save millions of lives in New York, according to researchers.
The researchers from Columbia University in New Orleans and University of California, Berkeley, have published their findings in the Journal of Mechanical Engineering.
The researchers were able to create a device that used a magnetic magnetic field.
They found that a broan fan can move air about a room, even if it is in an airtight box or chamber, and the fan’s size and shape are controlled by the magnetic field.
“The broan fans can be used to cool a room by using air currents that are generated from the walls, floors and ceilings,” the researchers said in a statement.
“In this work, we were able create an electromagnetically controlled broan flange that moves air in a room.
This new design is highly scalable and robust, and could be used in many types of rooms.”
The researchers’ broan system uses a pair of magnets that are attached to a wall and have a magnetic dipole in the middle.
These magnets are made of conductive copper and the two coils are connected with a pair or more wires.
The magnet that moves the air has a negative pole and a positive one.
The positive one is connected to a coil of wire that carries the magnetic energy.
The negative pole can be electrically connected to an electromechanical coil that controls the amount of current flowing through the coil.
“Our magnetic field creates an electric current that is flowing through a magnetic coil that drives a mechanical coil,” said study lead author and professor of mechanical engineering and electrical engineering in the College of Engineering at Columbia University, David Brokoff.
“If the magnetic coil has a magnetic energy that is strong enough, the electric current can be powerful enough to move the magnetic flux around a magnetically closed space, and thus generate enough magnetic energy to move that magnetically-closed space.”
The magnetic flux that moves around the broan has to be strong enough to lift and move air, which requires a very large magnetic field, the researchers explained.
A magnetic field of about 200 milliamps (mW) or more is required to create enough magnetic flux to move an airfoil through a broa.
The magnetic field needs to be low enough to create an electric field, and large enough to be sufficient to lift air and move it in the desired direction.
Broa fans, which have been in use for more than a century, are usually attached to the ceiling or walls.
The fans are small and cost about $3,000, and have two magnets attached to them.
Broan fans are ideal for low- and mid-level office spaces, but for larger offices they are not suitable.
“There are two types of broan in the market: those that move air and those that do not,” Brokoffs said.
“Both are fine in some situations, but neither is particularly well suited for larger spaces, such as conference rooms or conference rooms with a large number of occupants.”
The BroanFan project, which was led by Brokowski, is funded by the National Science Foundation and is led by the Brokowsky Laboratory at the Institute of Biomedical Engineering and Biomedical Sciences, Columbia University.
