When an electric current is reversed in an electromagnet, the magnetic field also reverses.
the magnetic field would constantly change, that's why the AC current is converted to DC current

When the circuit is interrupted, the current stops flowing.
When an electric pulse runs through an electromagnet, the current travels in the electromagnets coils, causing a magnetic field to be developed inside and outside of the coils. The amount of coils, tightness of the coils, and the space between the coils are all very important factors in the production of said EM field.
In that case, the magnetic field caused by the current would also be reversed. As for the wire itself, it would feel a force in the opposite direction, due to the interaction of the magnetic fields.

When you decrease the current in an electromagnet, the magnetic field decreases.
An electromagnet if formed by pushing current through a coil. If the circuit is truly open, current will cease to flow, thus no electromagnet.
As current increases, the electromagnet strength will increase.
The polarity of the electromagnet reverses.
The magnetic field reverses direction.

Many people are not aware of the fact that electric motors exist all around them. They are used in their car, washing machine, food processor, and so on. Even fewer people are aware of the way in which an electric motor actually works. Here are some of the basics. An electric motor is powered by the forces of electricity and magnetism. Magnets are used in order to create motion. Consider a simple magnet, with a north and south pole. The fact that a pole is attracted by its opposite and repulsed by the same is utilized in order to create the motion inside of an electric motor. The heart of the electric motor is the rotor, which is an electromagnet. An electromagnet consists of copper wiring that has been wound in a circle. When electricity moves in a circle, it creates a magnetic field. When electricity moves through the coil of wire, it becomes a magnet. When electricity is not passing through it, it is simply a coil of copper wiring. Inside an electric motor, there is at least one permanent magnet. When the electromagnet is activated, the north pole of the permanent magnet faces the north pole of the electromagnet. The permanent magnet is attached to an arm that can rotate around the electromagnet. Since the permanent magnet is repulsed by the north end of the electromagnet, it swings around to the other side. The direction of the electricity through the electromagnet is then reversed. This causes the north end of the electromagnet to become the south end. When this happens, the permanent magnet against swings over to the other side. This is the basic principle behind how all electric motors work. There are two basic types of electric motors: those that run on alternating current and those that run on direct current. A motor that runs on alternating current can take advantage of the fact that the direction of the electricity is constantly reversing in order to constantly reverse the polarity of the electromagnet and keep the electric motor running. In the case of direct current, a device known as a commutator is used in order to switch the direction of the current back and forth.
