A square frame made of 4 mm-thick iron rods and an
edge
length of 1 m is pushed into a homogeneous magnetic field of B=2 T
(T=Vs/m^2) with a constant speed of 15 m/s. Assuming the frame is
initially at room temperature (20°C).
a) Why does the frame heat up?
b)What is the temperature of the frame right after the experiment?
c) Now you pull it out of the B-field with the same constant speed, what is the temperature of the frame after it has felt the B-field completely?

In the figure, a 53.3 kg uniform square sign, of edge length
L = 1.67 m, is hung from a horizontal rod of length
dh = 2.71 m and negligible mass. A cable is
attached to the end of the rod and to a point on the wall at
distance dv = 4.41 m above the point where the
rod is hinged to the wall. (a) What is the tension
in the cable? (b) What is the horizontal component
of...
