## coils rotating in a magnetic field find maximum emf and magnetic feild strength

1. The problem statement, all variables and given/known data

coils rotating in a magnetic field are often used to measure unknown magnetic fields. As an example, consider a coil of diameter 2.00 cm with 72.0 turns that is rotated about an axis perpendicular to the field at a rate of 20.0 Hz. If the maximum induced emf in the coil is 6.00 V, find the strength of the magnetic field.
