Abstract:
A device may measure or detect, using at least one magnetic sensor, a magnetic field to determine whether a magnet is included within a charging device. In some examples, the device may include a receiving coil for charging of a battery based on magnetic induction. In response to determining that a magnet is present within the charging device, the device may instruct the charging device to adjust an amount of electrical current supplied to a transmitting coil.
