Question

A long wire is shaped into a coil that has 29 turns and a cross sectional area of 0.11 m2, and is placed in a uniform magnetic field. If the field changes strength from .312 T to .897 T in .48s, the absolute value of theemfinduced in the coil is _________ Volts. A flat coil of wire carrying a counter-clockwise current lies flat on a table. The magnetic field in the center of the coil is directed _______.
