Michael Faraday. Faraday heard of Oersted's work where electricity caused a magnet to move and figured that a moving magnet can make electricity. Faraday developed a homopolar generator that is similar to the electric power meter motors in many homes.
What else can I help you with?
Why are eddys formed in a conductor in an external magnetic field?
Eddy currents are electric currents that are produced inside conductors, through the process of changing the magnetic field in the conductor. The external magnetic field is used as a barrier or skin to protect the eddy.
How are electric currents and magnetism related?
Magnetism could be produced due to the flow of electrical current. This was first discovered by Oersted. By changing the magnetic flux linked with a coil electric current could be induced. This was first studied by Michael Faraday. Just due to the orbital motion or spin motion of electron magnetism is produced in tiny form and is known as magnetic dipoles. Such dipoles getting oriented in different form lead to form dia, para and ferro magnetic materials.
A magnetic field produced by a current has the characteristic?
The current must be changing. Say thank you to Faraday.
Can an electric current be produced by magnetism?
Yes, an electric current can be produced by magnetism through electromagnetic induction. When a magnetic field changes in intensity or moves relative to a wire, it induces an electric current in the wire. This phenomenon is the basis for how generators and transformers work.
What is magnetism produced by?
All magnetism is due to circulating electric currents or motion of electric charge. In magnetic materials the magnetism is produced by electrons orbiting within the atoms; in most substances the magnetic effects of different electrons cancel each other out, but in some, such as iron, a net magnetic field can be induced by aligning the atoms.
How electro magnetic produced?
Electromagnetic waves are produced by the acceleration of electric charges. When an electric charge is accelerated, it creates a changing electric field, which in turn produces a changing magnetic field. These changing electric and magnetic fields interact with each other, resulting in the generation of electromagnetic waves that propagate through space.
Can a changing magnetic field produce a steady electric field?
Yes, a changing magnetic field can induce a steady electric field. This is described by Faraday's law of electromagnetic induction, where a changing magnetic field creates an electric field in the surrounding space.
What causes electric magnetic wave?
Electromagnetic waves are caused by changing electric fields which create magnetic fields, and changing magnetic fields which create electric fields. These waves propagate through space at the speed of light and carry energy. They are produced by accelerating charged particles or by oscillating electric currents.
Can An electric current be produced by a changing magnetic force?
It's not the force. It's the changing magnetic field surrounding an electricalconductor, whether or not that conductor feels any force due to the field.
What are the physical significance of Maxwell's equations?
As per my knowledge,Maxwell's equations describes the relations between changing electric and magnetic fields. That means time varying electric field can be produced by time varying magnetic field and time varying magnetic field can be produced by time varying electric field.
Can an electric field exist without a magnetic field?
Yes, an electric field can exist without a magnetic field. Electric fields are produced by electric charges, while magnetic fields are produced by moving electric charges. So, in situations where there are stationary charges or no current flow, only an electric field is present.
What is a magnetic field will be produced at some point in space if the electric field at the point?
As far as the electric field is stationary then no magnetic field. But when electric field is moving at a uniform speed then a magnetic field will be produced. This is what we call Lorentz magnetic field.
When a blank wave that is produced by a vibrating electric charge is an electromagnetic wave?
When a vibrating electric charge produces a changing electric field, it in turn generates a changing magnetic field, leading to the creation of an electromagnetic wave. This wave consists of oscillating electric and magnetic fields that propagate through space at the speed of light.
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.
How do magnets magnetic fields electric currents and metals connect?
Magnets produce magnetic fields which can interact with electric currents to generate forces or induce currents in the conductive materials like metals. When an electric current flows through a metal conductor, a magnetic field is produced around it. This interaction forms the basis of electromagnetism and is used in various applications such as electric motors and generators.
How is a radiowave produced?
A radiowave is produced when an electric charge, such as an electron, accelerates and oscillates, creating a changing electric field. This changing electric field generates a corresponding magnetic field, and together they propagate through space as electromagnetic radiation. The process typically occurs in antennas, where alternating current generates oscillating electric charges that emit radiowaves.
How a magnetic field is produced?
A magnetic field is produced by moving electric charges. When electric charges move, they create a magnetic field around them. This magnetic field can interact with other magnetic fields and cause objects to be attracted or repelled.
