rotating cylinder produce magnetic field

Magnetic fields and how to make them

The magnetic field produced by currents in wir The simplest current we can come up with is a current flowing in a straight line, such as along a long straight wire The magnetic field from a such current-carrying wire actually wraps around the wire in circular loops, decreasing in magnitude with increasing distance from the wire.

Production of rotating magnetic field in polyphase stator

In an induction motor, when AC supply is given to the the stator, magnetic flux is produced which is revolving at synchronous speed This post will explain you in brief about production of rotating magnetic flux for 2 phase as well as 3 phase supply.

Does a rotating proton produce a magnetic field?

Mar 29, 2018· Protons already produce a magnetic field that is coupled to their spin I’m not sure what you mean by “rotating” The proton’s spin is partly due to the intrinsic angular momentum (spin) of its constituent quarks and partly due to the quarks’ orbi.

THE ROTATING MAGNETIC FIELD

Jan 05, 2016· THE ROTATING MAGNETIC FIELD Before we look at how the rotating field is produced, we should be clear what it actually is Because both the rotor and stator iron surfaces are smooth (apart from the regular slotting), and are separated by a small air gap, the flux produced by the stator windings crosses the air gap radially.

Rotating solenoid

Sep 11, 2016· I was thinking about Faraday's law, where a change in magnetic flux is necessary for an induced emf In this scenario, I am not sure where the changing magnetic flux comes from, since the magnetic field is constant and the area through which the magnetic field lines cross is constant, even if the solenoid itself is spinning (assuming the solenoid has radial symmetry).

The Field near an Infinite Cylinder

The Field near an Infinite Cylinder Remember when we were looking at electric fields inside and outside charged spherical shells? We used Gauss' Law to show that the field inside the shell was zero, and outside the shell the electric field was the same as the field from a point charge with a charge equal to the charge on the shell and placed at the center of the shell.
