Some electronic devices such as phones and watches can be charged wirelessly. In the charger, there is a coil that generates a rapidly changing magnetic field. In the device, there is a second, 100-turn rectangular coil with side lengths of 3.0 cm and 4.0 cm. If the maximum rate of change of the magnetic field in this second coil is 53 T/s, what is the emf induced in this coil?
