1-6. Figure 1-15 shows a coil of wire wrapped around an iron core. If
the flux in the core is given by the equation
ef, = 0.05 sin 377t       Wb
If there are 100 turns on the core what voltage is produced at the terminals of the  coil? Of what polarity is the voltage during the time when flux is increasing in the  reference
