An electromagnet is produced by an electric current. When an electric current flows through a coil of wire, it generates a magnetic field. The strength of the magnetic field can be controlled by adjusting the amount of current flowing through the coil.
Direct current (DC) is produced by an electric battery. This type of current flows consistently in one direction from the positive terminal to the negative terminal of the battery.
An electromagnet is a type of magnet that becomes magnetic when an electric current flows through it and loses its magnetism when the current is turned off.
Electromagnet. This is a type of magnet which the magnetic field is produced by the flow of electric current through wires generally surrounding a metal or iron core. Electric motors, generators, relays, loudspeakers, hard disks are examples of Electromagnets in other equipment.
An electromagnet is a type of temporary magnet that is created by passing an electric current through a coil of wire wrapped around a magnetic core, such as iron or steel. The strength of an electromagnet can be adjusted by changing the amount of electric current flowing through the coil.
Running an electric current through a soft iron core produces an electromagnet. Soft iron is easily magnetized and demagnetized, making it ideal for temporary magnet applications in devices like solenoids and electric motors. The magnetic field strength of an electromagnet can be controlled by adjusting the amount of current flowing through the coil.
An electromagnet is a type of magnet in which the magnetic field is produced by the flow of electric current. The magnetic field disappears when the current ceases.-wikipedia

temporary magnets Incorrect, it's electromagnetic.
a temporary magnet can be created by an electromagnet but it can also be created by any type of strong magnet
an electromagnet is a type of magnet that is created by an electric current. the magnetism disappears when the current is removed. if you have a landline phone and the phone line runs right next to a power line and you hear a buzzing in the line, you're hearing electromagnetic interference a permanent magnet is a type of magnet that is created by aligning the molecules by pole. this type of magnet will not lose it's magnetism in our lifetime.
