How can a simple electromagnet be made?
first, you have to have a ferromagnetic core, like an iron bolt. then, you wind a magnetic wire around it. the thicker the winding, the stronger the magnet. the tips of the wire should be protruding so you can connect it to a source. skin the tips of the wire, too. connect the wire to a dc source and you got an electromagnet.
What is gunn amplifier?
Answers.com says it is a microwave amplifier in which a Gunn oscillator functions as a negative-resistance amplifier when placed across the terminals of a microwave source.
What happens when a coil of wire cuts through a magnetic field?
If the magnetic field is fluctuating, or the coil of wire and magnetic field are moving with respect to each other, then a current is induced in the coil of wire. If the two are stationary and the magnetic field is stable, then no current is induced in the coil. However, if there is a current in the coil, from another source, then the coil and the field will exhibit a relative force that will tend to move the coil with respect to the field.
What does a armature or rotor do?
The Armature(or rotor) is a electromagnet inside a motor and alters the magnetic field inside the motor when it rotates. In DC motors it is connected to a Commutator. In AC induction motors the armature isn't connected to a power source.
When current flows in a conductor a magnetic field is created. The created magnetic field cuts the conductor which creates a voltage in the conductor. What is this voltage called?
It's called back EMF or reverse EMF. The EMF is electro-motive force, or voltage. What is happening is that the original current flow creates a magnetic field. That field then induces a voltage that opposes the original voltage that is causing the current flow. This back EMF "resists" the original voltage's efforts to cause current flow. If the created magnetic field did not oppose the original "efforts" of the voltage source to make current flow, then it would aid that voltage to make current flow. We would then get something for nothing and perpetual motion would be possible. We can't do that.
How did the earth get the magnetic field?
Because there's a magnet in the centre of the earth which is known that it's the source of gravity. It's magnetic field is around the earth obviously.
The source of magnetism is?
magnetic monopoles
Is the moon a source of earth's magnetic field?
No. The source of earth's magnetic field is the molten inner core. The moon due to its proximity of course influences our magnetic field but it is to be considered a "weak effect".
What are magnetic cars?
Magnetic air cars uses air compression as the source for propusion. It is "magnetic" in the sense that a magnetic motor is used for the air compression.
Is bauxite magnetic?
no but it the main source of aluminum
The source of the magnetic field on the Sun is?
the core
What is electromagnetic flux?
The electromagnetic force is a force that is expressed as (or that "shows up as") a "field" or a "group of lines of force" around the source. Electromagnetic flux is a direct reference to those magnetic lines of force. Electromagnetic flux is the electromagnetic field or the group of electromagnetic lines of force around the source. All the following sentences say the same thing: The electromagnetic flux around the magnet was very high. The magnetic flux around the magnet was very high. The magnetic field around the magnet was very large. The flux around the magnet was very high. The field around the magnet was very large. There were a large number of magnetic lines of force around the magnet making the field strength very high.
How do you control a magnetic field from a distance?
Surrounding a magnet with a magnetic shell can allow the magnetic field to move farther away from its source.
What are magnetic regions in iron called?
Magnetic domains.
Who determined the source of the earth's magnetic field?
The moon
What is the source of magnetic field of materials?
i have no idea yes
