# Playing with magnetic lines

My question is simple , I was just curious about this this it might seem stupid question but it should be thought upon , i was asking can we concentrate all magnetic lines at one place. Thanks in advance for giving your answer.

• A bar magnet does not have all magnetic field lines in one place. – BLAZE Jun 7 '17 at 18:04
• Sorry for the mistake but I was trying to ask that how can we concentrate magnetic field of bar magnet at one place. – user449276 Jun 7 '17 at 18:08

We have not observed such a thing. This statement is equivalent to one of Maxwell's equations: $\nabla\cdot B=0.$
