.Initial magnetic field strength: 
.Final magnetic field strength: 
.
is the magnetic flux linkage through the coil.
is the number of turns in the coil.
is the magnetic flux through the coil.
is the strength of the magnetic field,
is the area of the coil,
is the angle between the normal of the coil and the magnetic field. The coil is perpendicular to the magnetic field. As a result, the normal of the coil is parallel with the field. 
. 
. 
.
. As a result,
