I know that the poles of an electromagnet that is straight is at the ends but what if the metal core is an iron ring?
Would the poles be perpendicular to the ring's plane?mfb said:Then you have a circular magnetic field. This is called a toroid magnet, and you'll find it in various particle detectors, fusion reactors and probably a couple of other places.
And what is it about the magnetic field configuration (near the poles) that causes it to attract/repel other magnets? To keep things simple, suppose the "other magnets" are small (in physical size) compared to the magnet in question.kolleamm said:It would mean that it could attract/repel other magnets right?
A magnetic field is a region in space where a magnetic force can be detected. It is created by the movement of electric charges, such as electrons.
The magnetic field of a circular electromagnet is created by passing an electric current through a wire wrapped around a circular core. This current creates a magnetic field that wraps around the core in a circular shape.
The strength of the magnetic field of a circular electromagnet is affected by the number of turns in the wire, the amount of current flowing through the wire, and the material of the core.
The direction of the magnetic field of a circular electromagnet is determined by the right-hand rule. If you point your right thumb in the direction of the current flow, then your fingers will curl in the direction of the magnetic field.
The magnetic field of a circular electromagnet has various practical applications, such as in motors, generators, and magnetic levitation systems. It can also be used for scientific research and in medical imaging devices like MRI machines.
