Magnet Myths and Misconceptions

[Newton II]

You can define a magnetic field as a cloud of tiny purple honeybees swarming in tune to a Sosa march if you like.

I don't think honeybees are swarming!

Another interesting (crazy) observation :

It doesnot look like moving electrons produce magnetic field.  If moving electron produces magnetic field, then magnetic field should also move with the electron producing it.   Hence we should feel the force or vibration of moving magnetic field externally near a coil.

But practically we observe that when a direct current is passed through a coil, we get a static magnetic field at the centre of  coil and we don't feel any force (or vibration)  of a moving magnetic field.

Does it mean that when electron starts moving, mother nature provides it with an armour in the form of magnetic field to protect it from attacking enemies??!!!  Is magnetic field  produced by moving electron or nature? (vaccuum)

Can anybody explain why a moving electron current in a coil produces a static magnetic field at the centre?

What do you mean when you say "feel a force or vibration?"

What do you mean when you say "feel a force or vibration?"

What happens when you poke a straw man with a knitting needle?

What do you mean when you say "feel a force or vibration?"

I have said 'force or vibration of a moving magnetic field'. 


If you pass an AC through a coil and take a iron piece near the coil, iron piece vibrates indicating that the magnetic field produced by coil is in some sort motion or oscillation.

But if you pass a DC through the coil and bring a iron piece near it, you won't feel any vibration of the iron piece and it simply gets attracted to the coil indicating that magnetic field is stagnant.

My question is why moving electrons in a DC produce static magnetic field in the coil? 

What happens if you hammer a crowbar ( mega needle ) into strawman's ass ??

A continuous flow of unchanging DC current will produce a continuous unchanging magnetic field.  Easily confirmed by experimental observation.
