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 the change of the magnetic field and the second coil is 53 T/s, what is the EMF induced in this coil?

Answer:

Magnitude of induced emf will be equal to 6.36 volt

Explanation:

We have given number of turns N = 100

Dimension of rectangle is 3 cm and  cm

So area of rectangle

Rate of change of magnetic field

Induced emf is equal to

So magnitude of induced emf will be equal to 6.36 volt
