If you change the direction of current in an electromagnet, (which by the way is just a coil of wire) then the direction of the magnetic field will also be reversed: That is to say, what was north is now south. If you want more info. look up "the left hand rule".
If the direction of the current in an electromagnet is reversed, the direction of the magnetic field surrounding the electromagnet will also reverse. This change in direction will affect the polarity of the electromagnet, causing its north and south poles to switch.
The needle of the compass will align itself with the magnetic field produced by the electromagnet due to the flow of electric current in the coil. The compass needle will point in the direction of the magnetic field lines, which are generated by the current passing through the coil of the electromagnet.
If the current stops flowing through an electromagnet, the magnetic field that was being generated will also disappear. This will cause the electromagnet to lose its magnetic properties and no longer attract or repel magnetic materials.
An electromagnet must have a current flowing through its coil of wire in order to generate a magnetic field. When an electric current passes through the coil, it creates a magnetic field around the electromagnet.
When current flows through the wire around an electromagnet, a magnetic field is generated that strengthens the magnetic field within the core of the electromagnet. This causes the electromagnet to become magnetized and exhibit magnetic properties, such as attracting or repelling nearby magnetic materials.
If the direction of the current in an electromagnet is reversed, the direction of the magnetic field surrounding the electromagnet will also reverse. This change in direction will affect the polarity of the electromagnet, causing its north and south poles to switch.
Nothing - The polarity of an electromagnet depends on the direction of current flow and you can effect the same change in orientation to the earth's field by moving the electromagnet rather than the earth's field.

Direction of the magnetic lines too would get changed

the magnet is start picking things up

they would repel against one another well i don't really know go ask Ur mamma or dad whichever is smarter lolz
When we turn of the current in an electromagnet then electromagnet looses its magnetic property,provided the material used inside the current carrying solenoid is soft iron core. If, the material is steel then after the current is turned the magnetism propety still prevails and hence steel becomes a permanent magnet.
An electromagnet must have an electric current passing through its coils to generate a magnetic field. The magnetic field is created as the electric current causes the alignment of the magnetic domains within the core material of the electromagnet, creating a magnetic field around the coil.
Nothing just that it does not move to that direction
