Homework Answers
Solution) (1) True
Torque , T = NiABsin(theeta)
So it depends on orientation of magnetic field .
(2) True
Yes electrons have orbital magnetic moment.
(3) True
Torque is vector quantity . It has both magnitude and direction.
(4) True
Yes if two wires carry currents in same direction then they attract each other .

Question 5 (1 point) Which of the following statements are true? Select all that apply. Magnetic field inside an ideal solenoid is zero. When the magnetic dipole moment vector is oriented parallel to the magnetic field vector, the potential energy is minimized. In cyclotron motion in a uniform magnetic field, the period of motion depends on the magnetic field strength and the radius of the circle. In a velocity selector, both protons and electrons will pass through undeflected if they...

A rectangular loop has dimensions 0.505 m by 0.260 m. The loop
is hinged along the x-axis and lies in the xy-plane (see the figure
below). A uniform magnetic field of 1.45 T is directed at an angle
of 40.0° with respect to the positive y-axis and lies parallel
everywhere to the yz-plane. The loop carries a current of 0.855 A
in the direction shown. (Ignore gravitation.)
