Question

ve Proton. o eson. of wire with a resistance of 2. A laboratory technician makes a circular coil 300 loops of thin copper The coil diameter is 22.o em and the coil is connected to an o v battery. the the Cao Determine magnetic moment magnitude) co were placed between the pole faces of a the maximum torque on the coin if it magnet where the magnetic field strength was 0.75 T 3. The cube in Figure 3 is 25.0 cm on the edge. Four straight segments of wire bc, cd, and da form a closed loop that carries a current I b. 4.50 direction shown. A A in the uniform B 0.058 T is in the negative z-direction. Determine the magnitude and direction of the magnetic force on each segment. Figure 3.

Explanation / Answer

a) magnetic momment u = iA

                  = 300*0.22^2*pi*(18/0.65)

                 = 1263 Am^2

b) torque = u x B

              = 1263*0.75

               = 947 Nm
