How is a electromagnet diffrent then a permanent magnet?
An electromagnet is a temporary magnet that only produces a magnetic field when an electric current is flowing through it, while a permanent magnet retains its magnetism without needing an external electric current. Additionally, the strength of an electromagnet can be easily adjusted by changing the amount of current flowing through it, while the strength of a permanent magnet is fixed.
What magnet is created by an electric current?
An electromagnet is created by an electric current. When 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.
What type of magnet is produced by an electric current?
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.
Is a electromagnet a temporary magnet yes or no?
Yes, an electromagnet is a temporary magnet. It only exhibits magnetic properties when an electric current is flowing through it, and the magnetism disappears when the current is turned off.
What type of magnet is a electromagnet?
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.
What controls the strength of a magnet made with electric current?
The strength of a magnet(electromagnet) made by flowing electric current through a conducting coil depends on magnitude of current. . .
What magnet is created by an electric current?
An electromagnet is created by an electric current. When 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.

What type of magnet is produced by an electric current?
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.
What happens to the electric current if the magnet no longer moves in the coil?
The electrical current stops flowing.
Is a electromagnet a temporary magnet yes or no?
Yes, an electromagnet is a temporary magnet. It only exhibits magnetic properties when an electric current is flowing through it, and the magnetism disappears when the current is turned off.

What type of magnet is created when electric current flows through a coil wire?
An electromagnet is created when electric current flows through a coil of wire. This coil acts as a magnet when current is passed through it, allowing it to attract magnetic materials and exert a magnetic field. The strength of the electromagnet can be controlled by adjusting the amount of current flowing through the coil.
What must you have for an electromagnet to work that you don't need for a regular magnet?
To make an electromagnet work, you need an electric current flowing through a coil of wire, which is not needed for a regular magnet.
How is an electromagnet different from a refrigerator magnet?
An electromagnet is a temporary magnet created by passing an electric current through a coil of wire, while a refrigerator magnet is a permanent magnet that can hold items to a refrigerator or other magnetic surface without needing an electric current. Electromagnets can be turned on and off by controlling the electric current, while refrigerator magnets retain their magnetism without the need for an external power source.
What is an electromagnet different from a magnet?
An electromagnet is made by passing an electric current through a coil of wire, which produces a magnetic field. The strength of the magnetic field can be controlled by adjusting the amount of current flowing through the wire. In contrast, a magnet is a material that produces a magnetic field naturally without the need for an electric current.
What is a magnet that is creadted from electric current through a wire?
Electro-Magnet
