A15.4 cm diameter circular loop is made up of 20 loops of copper wire that has a measured resistance of 2.7 m. at what rate must the magnetic field change if an induced current of 15 a is needed in the loop? o 057 t/s o 1.7 t/s o 0.19 t/s

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

c) up

hope this
