Hi DLD
welcome to the forums :)

Magnetic Field is created when in-between wire charge flows.

not quite

a magnetic field is created around a conductor through which a current flows
( no "in-between" stuff ;) )

According to Faraday’s law we know that he got relativity in-between
electricity and magnetic.

have absolutely no idea what you are talking about there ?????

cheers
Dave

DLD if you are talking of force of a current carrying conductor placed in a magnetic field[relationship between magnetic field and electric field] then i think LORENTZ is the person to be talked about and not michael faraday, though faraday discovered electromagnetic induction, the relationship between magnetic and electric field was brought up by Lorentz. Fleming's right-hand rule can be use in detection of the direction of motion, magnetic field around the conductor and the induced current.

It is quite easy to build electromagnet.
You need to wrap insulated copper wire around an iron core making a coil.
A magnetic field will be generated around the wire when current flows through the wire.
The iron core will become magnetized and will concentrate the magnetic field within the coil and core.
The iron core will lose its magnetism when the coil is disconnected from the battery/power source.

I approved that last post although I don't reall yknow why, It doesn't make much sense to me.
