You are looking down on a single coil in a constant magnetic field B = 1.2 T which points directly into of the screen. The dimensions of the coil go from a = 8 cm and b = 17 cm, to a* = 16 cm and b* = 22 cm in t = 0.04 seconds. If the coil has resistance that remains constant at 1.2 ohms. What would be the magnitude of the induced current in amperes?

The  current is

Explanation:

From the question we are told that

   The  magnetic field is  

   The first length is  

    The  second length is  

    The first width is  

     The second  width is  

    The time interval  is  

     The resistance is  

Generally the first area is

=>    

=>    

The second area is  

=>  

=>    

Generally the induced emf is mathematically represented as

This negative show that it is moving in the opposite direction of the motion producing it

=>  

=>    

The induced current is

=>  

=>  

6/12=1/2

step-by-step explanation:

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator
