Question

How are magnetic field lines different from electric field lines and why is there a difference? If you break in half a metal rod with a positive charge on one end and a negative charge on the other, what do you end up with? What do you end up with if you break a bar magnet in half? What does this tell us about electric and magnetic monopoles?

Answer 1

The magnetic field  lines forms closed loops where as electric  lines won't form closed loops. This is because for magnetic poles source and Sink lies at lame point means we cannot able to Separate Nortn and South poles. where as positive & negative charges can be separated

• If we break a rod with  half with one positive and other  negative side  charge is allow two magneted where as if we have magnet & if it is broken, then is forms two magnets. This is because magnetic poles cannot be seperated where as electric charges can be separated.
• Magnet always exists in dipole but charge can exists as mono as well as bi.
