it is a tea with something floating on it.......
A coil with an iron core and a movable iron bar constitutes an electromagnet. When an electric current flows through the coil, it generates a magnetic field that attracts the iron bar, causing it to move. This device is commonly used in various applications such as in electric motors and doorbells.
Yes, an electromagnet can use a nickel core instead of iron. Nickel is a ferromagnetic material, meaning it can enhance the magnetic field produced by the coil of wire. However, iron generally offers higher magnetic permeability, which makes it more effective for most electromagnet applications. While nickel can work, it may not achieve the same strength of magnetism as an iron core would.
A coil of wire or a coil in the shape of a cylinder is a typical shape for an electromagnet (or a solenoid). The strength of the magnetic field of an electromagnet can be increased significantly if the coil is wrapped around an iron core. This configuration may be called an inductor when used as an element of an electrical circuit.
The two liquids tapped off from a blast furnace are molten iron and slag. Molten iron is the main product, while slag is a byproduct that is formed from impurities in the ore.
Do you maybe mean an 'iron core?' If so, an iron core strenghthens the magnetic field significantly. *If the coils are wound closer together the fluxlines are more dense and increase the strength of the field slightly (an iron core strengthens the field by allowing the magnetic field to propagate inside it better than air).

increase inductance
A cylindrical core of soft iron is used in a moving coil galvanometer because soft iron has high magnetic permeability, meaning it enhances the magnetic field produced by the coil. This helps increase the sensitivity and responsiveness of the galvanometer to small currents passing through the coil.
Soft iron has a greater permeability than steel. BTW, the only reason for laminations is to reduce eddy currents in the core. It has no effect on permeability or inductance.
When a coil of wire is wrapped around an iron core, an electromagnet is produced. The iron core enhances the strength of the magnetic field created by the current flowing through the wire, making it stronger than just a coil of wire on its own. This electromagnet can then be used in various applications such as electric motors, generators, and transformers.
The number of turns in the coil of wire, the electrical current flowing through the coil, and the presence of an iron core inside the coil.
no
This is a basic description of an electromagnet. Apply a voltage (direct current) to the coil, and a magnetic field will develop around the coil and be "conducted" through the iron core to create that electromagnet.
Electromagnet is a device consisting of a core of magnetic material such as iron, surrounded by a coil through which an electric current is passed to magnetize the core.
Coil tapped humbuckers definitely sound different than real single-coils. You can get usable clean tones with coil tapped humbuckers, but it won't be the same.
