Magnetic flux is a measurement of the total magnetic field that passes through a given area. Magnetic flux is a way of describing the amount of magnetic force on something of a given area. Answer and Explanation:1 A changing magnetic field induces an electric field. If a loop of wire is ...
Another unit of measure commonly used with magnets is the gauss (1 Tesla = 10,000 gauss). The magnets in use today in MRI are in the 0.5-Tesla to 3.0-Tesla range, or 5,000 to 30,000 gauss. Extremely powerful magnets -- up to 60 Tesla -- are used in research. Why are magnets ...
If you have a family history of breast cancer and are at high risk, your healthcare professional may order a breast MRI (magnetic resonance imaging) scan instead of a regular mammogram. This type of breast cancer screening uses radio waves and strong magnets to produce a detailed image of th...
Doctors useblood samplesfor genetic testing to identify defects or mutations that cause ALD . Doctors also use blood tests to evaluate how well your adrenal glands work. MRI. Powerful magnets and radio waves create detailed images of your brain in an MRI scan. What are the three most common ...

but the forces become larger as electrical currents increase. Experimental electromagnets have fields approaching 100 tesla -- about 30 times as strong as the powerful magnets used in magnetic resonance imaging (MRI) machines. Scientists run the magnets only for only two-hundredths of a second to ...
If you use a microwave, a car, a cell phone, a refrigerator, a laser pointer or a blender, you're using machines that were made possible by discoveries in physics. From jet aircraft to generators, motors to magnetic resonance imaging (MRI), physics-based inventions are ubiquitous in modern...
