Would electromagnetic waves exist if changing magnetic fields could produce electric fields but chaning electric fields could not in turn produce magnetic fields?
no
What brain imaging method uses radio waves and magnetic fields to produce a detailed image?
Electro-Magnetic imaging
How are magnets and motors related?
They both produce magnetic fields. So when together they attract.
What can most easily produce magnetic fields?
A naturally occurring stone called magnetite.
What are two ways to produce electric fields electric fields are produced by charged particles or by changing magnetic fields?
One way to produce an electric field is through the presence of charged particles. When charged particles, such as electrons or protons, are stationary or in motion, they generate an electric field around them. Another way to produce an electric field is through changing magnetic fields. According to Faraday's law of electromagnetic induction, a changing magnetic field induces an electric field, causing the flow of electric charges.
Would electromagnetic waves exist if changing magnetic fields could produce electric fields but chaning electric fields could not in turn produce magnetic fields?
no
Can all currents produce magnetic fields?
yes
How does magnets produce movement ina current carrying wire?
Faraday's Law states that magnetic fields produce a electric fields and vice versa. Also, Ampere's Law states that a change in magnetic fields w.r.t. time creates current.
Can Heavy objects falling in Gravitational fields Produce Electromagnetic fields?
Yes if the moon fell on earth it would definetly produce a noticable magnetic field.
What are the four Maxwell's equation?
Gauss's law: Electric charges produce an electric field. Gauss's law for magnetism: There are no magnetic monopoles. Faraday's law: Time-varying magnetic fields produce an electric field. Ampère's law: Steady currents and time-varying electric fields produce a magnetic field.
What are two fields surround a moving electric charge?
A moving electric charge will produce a magnetic field.A moving electric charge will produce a magnetic field.A moving electric charge will produce a magnetic field.A moving electric charge will produce a magnetic field.
What brain imaging method uses radio waves and magnetic fields to produce a detailed image?
Electro-Magnetic imaging
What do magnets have to with electricity?
Faraday showed that a wire passing through a magnetic field will produce electricity. This is how a generator works. Many windings of wire on an armature spin in a magnetic field. This makes electricity.
How are magnets and motors related?
They both produce magnetic fields. So when together they attract.
Only some currents are able to produce magnetic fields?
No. Any current produces a magnetic field. Look at Maxwell's equations.
Why do electrical machines produce less noise than fuel run machines?
A fuel ran machine uses combustion to obtain power, which therefore creates noise, an electrical machine uses the magnetic fields of electricity to obtain power which in return is silent, and there is the reason for the difference.
What can most easily produce magnetic fields?
A naturally occurring stone called magnetite.
