A student is given two pieces of iron and toldto determine if one or both of the pieces aremagnets. First, the student touches an end ofone piece to one end of the other. The twopieces of iron attract. Next, the student reversesone of the pieces and again touches the endstogether. The two pieces attract again. Whatdoes the student definitely know about theinitial magnetic properties of the two pieces ofiron?

Initially, when the two pieces are brought together, they attract. This is because either two of the…

An iron (density ρ) rod with length L, cross sectional area A, spans across two parallel, metal train tracks. The tracks are connected to a power supply and have a potential ∆V across them. Between the tracks are placed magnets such that the B-field points directly upwards with strength B. What is the acceleration of the iron rod be the moment it starts from rest? What will acceleration be as a function of speed as it continues? Assume the contact is frictionless between the tracks and the rod so that no force of friction needs to be overcome. What will the top speed of the rod be under these conditions?
