Yes.Pushoam said:So, the direction of magnetic field is circumferential. Is this correct?
I want to know about the argument. Is the argument correct?cnh1995 said:Yes.
Yes. In fact, there is no magnetic field outside the toroid.Pushoam said:I want to know about the argument. Is the argument correct?
I'm not an expert, but I don't think so. Factors like shape, symmetry, permeability of the material affect the field.Pushoam said:And is there anyway to generalize it for any cross-sectional shape?
A toroid is a type of magnetic core that is in the shape of a doughnut or ring. It is commonly used in electrical circuits and devices to create a magnetic field.
The direction of the magnetic field in a toroid is determined by the right-hand rule. This means that 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 direction of the magnetic field in a toroid is affected by the direction of the current flow, the number of turns in the coil, and the material of the core. Additionally, the shape and size of the toroid can also impact the direction of the magnetic field.
Yes, the direction of the magnetic field in a toroid can be reversed by changing the direction of the current flow. This can be done by switching the polarity of the power source or by reversing the direction of the coil.
A toroid's magnetic field is used in a variety of applications, such as in transformers, electromagnets, electric motors, and generators. It is also used in medical imaging machines, particle accelerators, and magnetic levitation systems.
