Complete Question

Suppose a wireless charging system of an electric toothbrush. The charger has Solenoid 1 with 800 turns and the toothbrush has Solenoid 2 with 150 turns. The current in the charger is 220 mA and the corresponding average magnetic flux through Solenoid 2 is 0.056 Wb. What is the mutual inductance of the pair of the solenoids?

The value is

Explanation:

From the question we are told that

     The number of turns of solenoid 1 is

     The  number of turns for solenoid 2 is  

     The current in the charger is  

      The  magnetic flux through solenoid 2 is  

Generally mutual inductance is mathematically represented as

=>    

=>    

more than, less

less than, more

the answer is 100. i just did this lesson and got a 100% on it. : )
