Acircular coil of wire of radius 8 cm and 19 turns is placed with its plane perpendicular to a 5.6 t magnetic field, produced by an electromagnet. the current to the electromagnet is then switched off, causing the magnetic field to collapse to zero in a time of 744 ms. what is the emf generated in the coil while the magnetic field is collapsing, in units of volts?
