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.

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.
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.
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, a moving electric charge creates a magnetic field
What is magnetism produced by?
Magnetism is produced by the alignment and movement of electric charges, specifically electrons, within a material. In some materials, such as iron, nickel, and cobalt, the alignment of these charges creates a net magnetic field that can attract or repel other magnetic materials.
Can a changing magnetic field produce a steady electric field?
Not a steady but a moving electric field can be produced by ever changing magnetic field.
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.
How do magnets magnetic fields electric currents and metals connect?
Well when an electric current flows through a conductor a magnetic field is produced. And a changing magnetic flux through a conductor produces a current in the conductor.
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.
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.
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.
Where did Hans Oersted live?
Hans Christian Ørsted (or Oersted) lived in Denmark. He discovered the magnetic field produced by an electric current.

Why does a metallic piece become hot when it is surrounded by a coil carrying high frequency alternating current?
This is because of the eddy curents produced due to the changing electric and magnetic fields.
How is an EM wave produced?
By the interactions of Electric and Magnetic fields perpendicular to it.
