A circular wire coil of radius 25 cm and 20 turns is sitting in a perpendicular magnetic field of 0.20 T. If the coil is rotated 90°, what is the magnitude of the change in magnetic flux through the loop? a) 0 Wb b) 1.6 Wb c) 0.080 Wb d) 0.80 Wb e) 0.040 Wb

c. rb

explanation:

the atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons.
