What materials are needed to make electromagnet?
-- a DC power supply; (e.g., battery) -- a long conductor that can be arranged to take the current several turns around a central axis; (e.g., wire) -- a highly permeable core for the winding; (e.g., cylindrical clump of iron)
What intermolecular force acts within a metal wire?
The forces which hold a metal together are called metallic bonds. They consist of delocalised electrons which bind all the atoms together.
Four factors that determine resistance of an object?
Length, cross section, material, temperature.AnswerWithout wishing to sound pedantic, there are only threefactors that affect resistance. These are the length, cross-sectional area, and resistivity of a material. Temperature affects resistivity.
What are the components of an electromagnet?
Coil and core, and you'll need a power supply to activate it.
Is it ok to weld galvanized steel with a mig using flux core wire?
Yes but make sure you do not breathe in the vaporized Zinc fumes, it can make you very ill
Jacket is the terms desrribes the metallic core of a wire?
The answer is Armor
What is the metallic core of a wire called?
A conductor
What Describes the metallic core of a wire?
conductor
What is an example of an example of metallic bonds?
all metals are metallic bonding. use any one of them all metals are metallic bonding. use any one of them
Can you double the length of a metallic wire by applying force over it?
No, applying force to a metallic wire will not double its length. The length of the wire is determined by its physical properties and cannot be changed by force alone.
The development history of enameled wire?
The aluminum core magnet wire, as the name suggests, refers to the magnet wire with aluminum as the core.
What type of bond occur in cooper wire?
In a copper wire, metallic bonding occurs. Metallic bonding is the type of bonding where electrons are delocalized and free to move throughout the structure, giving metals their unique properties such as conductivity and malleability.
Metal core wire and what are needed to make an electromagnet?
To make an electromagnet, you would need a metal core wire (such as iron or steel) and a power source, such as a battery or electrical current. The metal core wire is wrapped around a core material and the electricity passing through the wire creates a magnetic field around the core, resulting in the electromagnet.
Difference between 2 core wire and 4 core wire?
in 4 core cable all four cables are equal dia and in a 3.5 core cable 3 cores are equal dia and fourth one will be with half dia. and it is used for neutral in 3phase 4 wire syastem
What happen to the resistance of metallic wire if it is heatedExplain?
Its resistance increases. This is because of vibrations of the core of atoms and so they have got good influence over the movement of electrons. So conductivity gets reduced and so resistance increases. This is what we call positive temperature coefficient
How strong is a electromagnet?
Well, it depends on the core you use, the thickness of the wire, how much the wire is coiled around the core, and especially the power supply.
