What is toroidal magnet?

Magnetic Field of Toroi. The toroid is a useful device used in everything from tape heads to tokamaks. Magnetic field = permeability x turn density x current. For a solenoid of radius r = m with N = turns, the turn density is n=N/(2?r)= turns/m. If the current in the solenoid is I = amperes.

What happens if you cut a magnet in half?

A bundle of tiny magnets, called magnetic domains, are jammed together. The magnetic fields of the others are reinforced by each one. Each one has a small pole. The new faces will become the new north or south poles of the smaller pieces if you cut one in half.

Is is possible to have no magnetic field for a moving electron?

However there is a magnetic dipole due to the motion of the electrons. No you can have a magnetic field without an electric field. Consider a rod with an equal number of positive and negative charges (such that they are equally spaced). Why magnetic field is half at the end of solenoid? Answer: It becomes half because themagnetic field strength on the axis going right through the solenoid, in the place on the end of thesolenoid is then the field of an infinitely long solenoid minus halfof it because half is missing, and so the field strength is half as big on the ends (but right in the middle).

Is there no magnetic field inside a toroid?

Therefore, any point in the empty space surrounded by a toroid will have a magnetic field, B equal to zero. The magnetic field is zero because the net current in this space is zero. Keeping this in consideration, what is m in m nia? Magnetic dipole moment of a current carrying loop is given by. M = IA. For N such turns M = NIA. Where I = current and A = area of cross-section of the coil.

Thereof, what is a tesla physics?
