Why does the wire on an electric motor have to be coiled?
To form the magnetic field that rotates the motor. :)
Is a magnetic field needed to create gravity?
No.
What creates magnetic fields?
Basically moving electric charges will create a magnetic field.
Does a lodestone create a magnetic field?
A lodestone is magnetized and thus produces a magnetic field around it. This can be detected by the deflection of a compass needle.
Can we create magnetic field to electric field?
we can create electromotive force (and electric current) by changing magnetic field linked with a conductor by the principle of electromagnetic induction which is governed by the Faraday's and Lenz's law. But electric field is created by statical electricity.
The combination of the magnetic field of the coiled wire and the iron create a very what magnet?
The combination of the magnetic field of a coiled wire wrapped around an iron core will create a very useful electromagnet. This is the bases used in the construction of mechanical relays.
Magnetic field of the coiled wire and the iron wire create a very high or low magnet?
Yes
Why does the wire on an electric motor have to be coiled?
To form the magnetic field that rotates the motor. :)
How is a magnetic force in an electromagnet created?
An electromagnet uses electricity to create the magnetic field. Moving charges create magnetic fields. Knowing that, if we have a lot of copper wire (with a suitable insulator) wrapped around an iron core, we can send direct current through that wire, and it will create a magnetic field. The magnetic field will magnetize the iron core, and the core becomes a magnet. Wrapping wire around a nail and connecting a battery to the ends of the wire will make a simple electromagnet.
Can a moving electric charge create a magnetic field?
Yes. A spinning charge will create a magnetic field as will a moving charge.
Electric current that moves through a coiled wire wrapped about a piece of iron creates?
Magnetic field.
What does a electromagnet create?
a magnetic field
What is generated when a permanent magnet is moved in front of a coiled wire and the magnet's magnetic field pushes and pulls electrons in the coiled wire?
an AC, or alternating current
Is a magnetic field needed to create gravity?
No.
What creates magnetic fields?
Basically moving electric charges will create a magnetic field.
When DC is past throgh coil of wire what is formed?
When a current is passed through coiled wire, the wire will store some of that energy in a magnetic field. As soon as the source of the current is removed, the engergy in the magnetic field will return to the wire.
What is magnetic in electromagneticism?
Maxwell's equations state that electric fields create magnetic fields, and vice versa. If you have a current, you have a magnetic field. If you have magnets, you have an electric field.
