What device works by rotating a wire coil within a magnetic field to produce electric current?
inductor
What does a Rotating magnetic field do?
The Field which is continuously rotating with a particular axis is known as rotating magnetic field. It will be created in Three phase induction motor's stator. When the supply is given to stator of three induction motor, the flux of each phases (that are displaced by 120 degrees) will interact. Due to this the resultant Field will be rotating Magnetic Field will be Produced.
Can a dc electric field produce magnetic field?
Yes. A steady current will produce a magnetic field, B= uI/r
Whats meant by radial magnetic field?
A radial magnetic field ensures that the plane of the coil (rotating within the magnetic field, in say a DC motor) is always flat within the external magnetic field ensuring maximum torque in (nearly) all positions. Hope this helps!
What causes a magnetic field to be set up around a wire?
Passing an electric current through a wire will produce an external magnetic field. This is because the electrons have spin and this spin is what produces the field. Spinning electrons (of certain characteristics) also produce the magnetic field of permanent magnets. And no spinning electrons, no magnetic field.

How is an electromagnet different from a regular a magnet?
An magnet is a material or object that creates a magnetic field. Bar magnets constantly create their magnetic field, while electromagnets are coils that only produce a magnetic field when an electric current passes through it.

What is the different electromagnets and permanent magnet?
Electromagnets are non permanent magnets. They got magnetic field because of applied electric field. They lost their magnetic field which was around that, when the applied electric field is stopped. permanent magnets have magnetic property always with it. Permanent magnetic property loses when we heat the material. It cannot be regained once again. But electromagnets are capable of regaining its magnetic properties.
Name the types of alternators based on their rotor construction?
1) Rotating armature alternator, rotates in stationary magnetic field. 2) Rotating field alternator, the magnetic field is rotating.
