Electro-Magnet
A magnet created when electric current flows through a coil of wire is called an electromagnet.
The strength of a magnet(electromagnet) made by flowing electric current through a conducting coil depends on magnitude of current. . .
A magnet that becomes energised when an electric current is passed through it.
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.
An electromagnet is a magnet while an electric current is running through the coil. Turn off the current and it is no longer magnetised, and is, therefore, not a permanent magnet.
No, there will be no induced electric current if the magnet remains at rest relative to the conductor. Movement or a change in magnetic field is required to induce an electric current in a nearby conductor through electromagnetic induction.
No, an electromagnet is not a permanent magnet. It is a magnet that produces a magnetic field when an electric current is passed through it, and the magnetic field disappears when the current is turned off.
A magnet cannot stop an electric current, but it can influence the flow of the current. Moving a magnet near a wire carrying an electric current can induce a voltage in the wire, which can affect the behavior of the current.
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.
a moving coil and moving magnet
An electric current can be created by moving a magnet through a metal coil.
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.
