(c19p12) A slender, 300- g bar magnet 25.0 cm long has a
magnetic moment of 5.90 A m2. It is held at an angle of
45 o to the direction of a uniform magnetic field. When
released, it begins to rotate about its center with an initial
angular acceleration of 5.87×102 rad/s2. What
is the magnitude of the magnetic field?
Homework Answers
Torque, T = u B sin(theta)
T = 5.90 x B sin(45) = 4.17 B
T = I a
4.17 B = (0.3 x 0.25^2/12) x 587
Magnetic field, B = 0.22 T

The 600 mm long homogeneous slender bar OA has a mass of 8 kg and is supported in the horizontal position by the cable at A and the corner hinge at O
The 600 mm long homogeneous slender bar OA has a mass of 8 kg and is supported in the horizontal position by the cable at A and the corner hinge at O. The cable at A is suddenly released. Just before hitting the incline, the bar has an angular velocity of ω= 5 rad / sec. Calculate the angle θ. Neglect the curvature of the path of the bar mass center when the bar is falling and assume that the...
