What is a 2 torus?

The 2-torus, sometimes simply called the torus, is defined as the product (equipped with the product topology) of two circles, i.e., it is defined as . The 2-torus is also denoted . The term torus more generally refers to a product of finitely many copies of the circle, equipped with the product topology.

Then, what are tokamaks used for? tokamak, Device used in nuclear-fusion research for magnetic confinement of plasma. It consists of a complex system of magnetic fields that confine the plasma of reactive charged particles in a hollow, doughnut-shaped container.

Do humans have a magnetic field?

Today, two hundred years later, we know that the human body is indeed magnetic in the sense that the body is a source of magnetic fields, but this body magnetism is very different from that imagined by Mesmer. What is the difference between solenoid and toroid? A toroid turns, and with those turns induces a higher frequency. Difference between Solenoid and Toroid. Solenoid Toroid Magnetic field is created outside Magnetic field is created within Magnetic field is created outside It does not have a uniform magnetic field inside it. Has uniform magnetic field inside it. Magnetic feild Outside :- magnetic field (B) 3 more rows ?

Regarding this, what is the magnetic moment of toroid?

Answer: (c)In case of a toroid, the magnetic field is only confined inside the body of toroid in the form of concentric magnetic lines of force and there is no magnetic field outside the body of toroid. Thus the magnetic moment of toroid is zero. What is the magnetic field of a toroid? The magnetic field is zero because the net current in this space is zero. Thus, the magnetic moment of the toroid is zero.
