104. A student is given two pieces of iron and told
to determine if one or both of the pieces are
magnets. First, the student touches an end of
one piece to one end of the other. The two
pieces of iron attract. Next, the student reverses
one of the pieces and again touches the ends
together. The two pieces attract again. What
does the student definitely know about the
initial magnetic properties of the two pieces of
iron? [1]
107. Which diagram best represents the lines of
magnetic flux between the ends of two bar
magnets?
