Now
a days, we heard of wireless charging of mobiles through power mats. The basic
concept of wireless charging is in faraday's law, the law states that whenever
a conductor is placed in time changing electric field an emf(Electro motive
force) called as voltage is induced in that particular conductor. This concept
is used and is applied to wireless charging of devices.
Whenever
a mobile is placed in power mats, this power mats are capable of emitting
alternating current which will create a magnetic field and mobile is equipped
with conductor(wireless charging contacts), and now according to the law, this
magnetic field will induce the voltage in the conductor and the mobile gets
charged
.
Only
power mat need to be plugged in. With this concept, with one plug and one cord
we can charge many devices by placing on power mat.
