This was Hans Christian Ørsted. April 1820 - Copenhagen.
He found that a compass needle could be deflected (it moved) if a current was switched on or off in a nearby conductor. This was the first demonstrated link between electricity and magnetism, later taken up in detail by Michael Faraday.
Oersted did not develop his experiment into an electric motor, though it is the basic idea on which all motors work - the interaction of an electric current with a magnet (usually in modern motors an electromagnet of some kind) to produce a force, and thus a movement.
What else can I help you with?
Where did Hans Oersted live?
Hans Christian Ørsted (or Oersted) lived in Denmark. He discovered the magnetic field produced by an electric current.
What is the Force that pushes or pulls magnetic material near a magnet?
Magnetic forces are produced by the motion of charged particles such as electrons. Magnetism is one of the fundamental forces of nature.
What provides electromagnetic waves?
In atoms, when they are affected by energy, the electrons will get excited and move up to a higher energy state. When they relaxe and move back down, the extra energy gets shot out as an electro magnetic wave (photon, or light)
Why are materials magnetic?
the materials are magnetic because of electromagnetic forces and this force is produced because of presence of positive and negative charges in them
What is a control test tube?
There are many uses of the electromagnet, it is used to invent generators and electric motors, used it to control the switch relay, use in practical industries, and even in an electric bell etc. Because the electromagnet is a type of magnet in which the magnetic field is produced by the electric current.
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.
Where did Hans Oersted live?
Hans Christian Ørsted (or Oersted) lived in Denmark. He discovered the magnetic field produced by an electric current.
How do moving electric charges and magnets interact?
Moving electric charges produce a magnetic field, which can interact with other magnetic fields, including those produced by permanent magnets. This interaction can result in forces being exerted on the moving charges and/or the magnets, leading to phenomena such as magnetism, electromagnetic induction, and electric motors.
Where did Hans Christian Oersted live?
Hans Christian Ørsted (or Oersted) lived in Denmark. He discovered the magnetic field produced by an electric current.
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.
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.
What is the difference between electric and magnetic fields?
Electric fields are created by electric charges and exert forces on other charges, while magnetic fields are created by moving electric charges and exert forces on other moving charges. In summary, electric fields are produced by stationary charges, while magnetic fields are produced by moving charges.
How is an EM wave produced?
By the interactions of Electric and Magnetic fields perpendicular to it.
How is EM wave produced?
By the interactions of Electric and Magnetic fields perpendicular to it.
What are the differences between electric fields and magnetic fields?
Electric fields are created by electric charges and exert forces on other charges, while magnetic fields are created by moving electric charges and exert forces on moving charges. Electric fields are produced by stationary charges, while magnetic fields are produced by moving charges. Additionally, electric fields can be shielded by conductive materials, while magnetic fields can penetrate most materials.
What is the difference between electromagnetic and magnetic fields?
Electromagnetic fields are a combination of electric and magnetic fields that oscillate and propagate through space, carrying energy. Magnetic fields, on the other hand, are produced by moving electric charges and exert forces on other moving charges. In summary, electromagnetic fields involve both electric and magnetic components, while magnetic fields are solely produced by moving electric charges.
