Suppose you have a square coil and a triangular coil each havesides of length L. The triangular coil has twice as many turns asthe square coil. Suppose that the same current is sent through eachcoil, when the coils are placed in the same uniform magnetic fieldmaking an angle of 30° with the planes of the coils, which coilexperiences the greater torque?


Is it:
--both coils experience the same torque, ----depends on themagnitude of the magnetic field that the coils are placed in ,-----triangular coil,----- or is it the square coil?

A solenoid consists of N = 110 turns of wire length d= 6 cm and cross-sectional area A = 3 cm2. Assume that the magnetic field inside the solenoid and ignore end effects. 

 

(a) Write an equation for the magnetic field B produced by the solenoid. Express the answer in terms of the current through the coil I, the number of turns N, length of the coil d, and permeability of free space   .

 

(b) Using the equation for the magnetic field determined in part (a), calculated the magnetic flux, in webers, through a single loop of the solenoid with a current of I = 1.9 A. The coil is d = 6 cm long and has a cross-sectional area of 3 cm2 and consists of 110 turns. 

 

(c) The self inductance related the magnetic flux linkage to the current through the coil. Calculate the self inductance L in units of . THe coil is d = 6 cm long and has a cross-sectional area A = 3 cm2 and consists of N =110 turns. 

If a coil of 150 turns is linked with a flux of 0.01Wb when carrying a current of 10A. If this current is uniformly reversed in 0.1 second, the induced EMF is __
