What was the significance of core?
Core, I am assuming, means "magnetic core memory". This was an early type of persistent memory used on early computers. You could put a core on a shelf and pull it down for use several years later, and it would still have the data in memory as it was the day you put it on the shelf. Core memory was used as permanent random-access memory on early computers A very small magnetic doughnut (a single core) would have three wires passed through it. Two wires would be used to set or read the position of the magnetic field of the particular core doughnut. A third wire was used to carry the signal if the field was reversed. All magnetic fields can be reversed by creating a nearby magnetic field at sufficient strength. Current in one of the address wires was insufficient to cause a change in the magnetic field of the doughnut core. But when both address wires carried current at the same time, the magnetic field generated would flip the field of the core to align with the field produced by the current in the address wires. When one of these tiny doughnuts switched magnetic poles a current was then introduced into the sensor wire and read as a change that might indicate a 1 or a zero. The machine would then put the core back the way it was to preserve that value stored in that memory location. All of this wiring using these very tiny doughnuts of magnetic material was difficult and cost a lot of money to produce. It was all they had for permanent storage until transistors came into common use.
Articles of confederation needed to be changed to form what kind of government?
To a stronger central government. They didn't work because everyone was an individual and not united under a single working government.
What dose the continental drift theory state?
It states that all the continents were once a single supercontinent and broke up and drifted to their current locations.
Can a go inside a closing quotation mark?
Typically, only full or partial sentences will be put in quotation marks. Very rarely will there be quotation marks around a single article, however, it can happen.
Is FDR single?
No, FDR is not single.
How does the magnetic field around a current carrying wire change as the wire is formed into a coil?
When a straight current-carrying wire is formed into a coil, the magnetic field becomes concentrated inside the coil due to the additive contribution of each turn of the wire. This results in a stronger and more uniform magnetic field inside the coil compared to a single straight wire. The direction of the magnetic field around the coil follows the right-hand grip rule.
In an electromagnet how do you make a stronger magnetic field with a single wire?
according to ampere's circuital law,magnetic field is directly proportional to the current flowing through the conductor.thus magnetic field can be increased by increasing the current through the conductor,provided the conductor or wire is capable of carrying high currents i.e. it should be of good conductance.
Why cant a single current carrying conductor be installed within a metal raceway?
A single current-carrying conductor inside a metal raceway can create electromagnetic fields that induce eddy currents in the raceway, causing increased resistance and heating. This can lead to overheating and potentially a fire hazard. Multiple conductors in the raceway can help balance the magnetic fields and minimize these effects.
Why electric not attract iron objects when current is passed through it?
Any electric current does generate a magnetic field, but it might be a very weak magnetic field that you would not notice. In order to create a powerful electromagnet, wire is wrapped around a ferromagnetic core, typically hundreds or thousands of times. Each coil of the wire adds to the magnetic field. But unless the current is extremely strong, a single straight wire produces a magnetic field that's quite weak, but it IS strong enough to deflect a nearby magnetic compass.
What is the main difference between an electromagnet and a solenoid?
An electromagnet is a type of magnet where the magnetic field is produced by an electric current, while a solenoid is a coil of wire used to create a magnetic field when an electric current is passed through it. In simpler terms, an electromagnet is a magnet that can be turned on and off using electricity, while a solenoid is a simple coil of wire used to create a magnetic field.
Why Non metalic gland plate is required for single co?
Dear... As we know that acable carrying alternating current has a alternating magnetic field (Flux)surrounding it. And also we know that when a magnetic flux linked with magnetic material changes, an emf is indused in it which circulates a current in it provided a closed path. Now in case of three core cable or 3.5 core cables, the net magnetic field prodused by all pahses ( and nutral ) due to currents, sum to zero. But in case of single core cable it has a net flux surrounding it. which if linked with MS ( magnetic Gland palate) will induce eddy currents in it which may result i heating of glands and successivelly failure of insulation of cable due to heat. So in case of single core cables, aluminum (non magnetic) gland plate is used)... Hope this will be sufficient to convince you... anuj rawat anujgul@yahoo.com
Does Uruguay have a magnetic field?
The earth as a single object has a magnetic field. If Uruguay is part of the earth, it shares the earth's magnetic field.
What purpose does a capacitor serve in a single phase motor?
These are actually single-phase induction motors. There is no electrical connection to the armature itself. To make the armature turn within the windings an electric current has to be induced in the it, and this is done by making the magnetic field move in relation to the armature. (The same principle is involved as moving a magnet over a wire to get an electric current.) With an electric current flowing in the armature there is a magnetic field set up around it which pushes against the magnetic field in the windings to make the armature turn.OK, but how to make the magnetic field move? That's the purpose of the capacitor.Capacitors have the property of advancing alternating current by (if I remember correctly) 90 degrees. In the simplest case, there are two windings in one of these motors. Unaltered electric current is sent through one of the windings. Some electric current is sent through the other winding and a capacitor. Now, because the two windings are being energised by currents that are out of phase by 90 degrees it is as if the magnetic field is moving. The armature responds by moving.
What are 3 ways to magnetize an object?
Rubbing a magnet against the object in a single direction to align its magnetic domains. Applying an electric current to the object to induce magnetism through electromagnetism. Exposing the object to a strong magnetic field to align its magnetic domains.
Revolving field theory of single phase induction motors?
The revolving field theory of single-phase induction motors suggests that a rotating magnetic field created by current flowing through two windings (main and auxiliary or starting winding) produces a starting torque in the rotor. This theory explains how single-phase motors can operate without the need for a separate rotating magnetic field, as in three-phase motors, by using a split-phase or capacitor start design to generate a rotating magnetic field.
Is hydrogen magnetic in any way?
Hydrogen has a magnetic moment due to its single proton in the nucleus. This makes hydrogen weakly magnetic, but its magnetic properties are not significant for most practical purposes.
A clamp on ammeter measures?
Measures current by magnetic field induced into the clamp. You need to clamp a single conductor. For example you couldn't just clamp a lamp cord since it has two conductors and the current is going in opposite directions and the fields cancel each other out.
