Airport security checks use walk-through metal detectors that detect changes in magnetic field. If the walk through area has a width of 1.0 m and a height of 2.2 m and is pulsed with a magnetic field of 0.0004 Tesla, what is the flux assuming no angle is involved? [Select] GARRETT Airports may also use handheld wand metal detectors, like the one shown above. They emit magnetic fields of about 0.000008 Tesla. When using these wands, how much less exposure to magnetic fields does the human body encounter compared to the magnetic fields of a walk- through detector? [Select]
Magnetic flux describes the magnetic field through a surface. The left picture shows a view of pink magnetic field lines emerging from the page through a loop. The picture on the right shows another loop tilted with respect to magnetic field lines going through it.
To find magnetic flux, use the formula
where
is the magnetic flux, B is the magnetic field, A is the cross sectional area, and is the angle between the electric field lines and the normal (perpendicular) to the surface area A. The units for flux is Webers (Wb) which is equivalent to Teslam
