A long solenoid has n = 400 turns/m and carries a current I = 30 A(1 - e-1.6t/s). Inside the solenoid and coaxial with it is a loop that has a radius R = 0.06 m and consists of N = 250 turns of wire (Fig. 3). What is the emf induced in the loop?
I know that the inuced emf is N(deltaBA/deltat)...
One end of a uniform 4.00-m long rod of weight Fg is supported by a cable. The other end rests against the wall, where it is held by friction. The coefficient of static friction between the wall and the rod is = 0.500. Determine the minimum distance x from point A at which an additional...
