Like charges repel each other while opposite charges attract each other.
Magnetic dipole is due to two poles of magnet. Electric dipole is due to +ve and -ve charges of electric charges.
They repel each other.
electric current in a solenoid coil
the electric current is generated by the electric field. thus by the left hand rule when current is passed through a conductor a magnetic field is generated around it so that it is a similar act of a magnet. thus it seems to be a magnet.
No, but if you drop a really strong magnet through a narrow copper tube it has a really cool effect (electric charges affecting magnetism)
..because of coil it creates magnetic field through the magnet, the coil contains electric charges and it continue to move, upward and downward. The significant of coil is to store electric charges.
electric current in a solenoid coil
One important difference is that electric charges can be separated. A magnet ALWAYS has a north pole and a south pole, which you can't separate. If you cut a magnet in twain, you'll get two magnets, each with a north and a south pole. Some modern theories propose the possibility of magnetic monopoles, but so far, in practice, these have not been discovered.
The magnetic field produced by electric current in a solenoid coil is similar to that of a bar magnet.
Any time there is ANY flow of electric charges (any current), the current will be surrounded by a magnetic field.
An electo-magnet is used in an electric bell.
A negative charge will repel a negative charge.
