Magnetic Flux Worksheet
1.
A 3 m by 4 m rectangle of wire is exposed to a magnetic field of 4 T. The magnet field lines
and the normal to the plane of the rectangle make an angle of 55 degrees. What is the
magnetic flux of the rectangle?
2.
Jacob is pedaling his bike down the street perpendicular to the earth’s magnetic field of 5.5 x
10-5 T. What is the flux through the metal rim of his bicycle wheel, if the wheel has an area of
1.13 m2?
3.
A medical process called magnetic resonance imaging (MRI) replaced X-rays in some
instances where pictures are required to study soft internal organs. Nancy is undergoing an
MRI procedure and is placed inside a chamber housing the coil of a large electromagnet that
has a radius of 25.0 cm. A flux of 0.290 Wb passes through the coil. What is the strength of the
magnetic field inside the coil?
