1. The current I through a long solenoid with n turns per meter and radius 0.30m is changing with time as given by /=sin(120t). The magnetic field inside a solenoid is given by B=nuol where Ho is the free space permeability Ho=1.26-10-6 H/m. What is the magnetic flux through a single coil at a time of t= 1.1 s at distance r= 0.25 m from the center of the solenoid if there are, n=108 turns/m? a) Start by determining the flux through a gaussian loop of radius r=0.25 m centered in the middle of the solenoid. Hint: Is the angle for the sine function in degrees or radians? B=nuosin(120t) ²2²= VTm² b) Next determine the rate of change of the magnetic flux with time d (nuosin(120t)²) = Tm²/s dt $B= d dt |§E·a|-|-dd₂| Recall that the symmetry of the c) The electic field can then be determined from dt problem means the electric field is constant when integrating around the loop. E= V/m
