This quantity can be defined as the sum of the cross product of velocity and magnetic field along a path, or it can be defined as the sum of the electric field along a path.
This quantity can be defined as the sum of the cross product of velocity and magnetic field along a path, or it can be defined as the sum of the electric field along a path. Faraday's Law defines it as the negative rate of change of the magnetic flux with respect to time, and Lenz's Law says that it is in such a direction as to oppose change in magnetic flux. For ten points, name this quantity, usually measured in volts, with abbreviation emf.
