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?
