CBSE X Physics Magnetic Effects of Electric Current
my teacher today taught that when you bring an iron nail or any metal thing it get magnetized , but i think that if i took an iron bar and brought it near a bar magnet , if it were to be magnetized then it would have poles so one end of iron bar should repel but this does not happen . why? and ?
