What shape should be given to the wire so that, in the presence of current in it, the lines of force of its magnetic field are located in the same way as that of a strip magnet?
In order for the magnetic field lines around the current-carrying conductor to be located in the same way as for a strip magnet, the conductor must be wound on a long coil. Such a current coil will have two poles: the north and south, while the lines will be located similarly to the strip magnet field
