McKinney, Ramesh Narayan, Alexander Tchekhovskoy , Rebecca Shafee, Jeffrey E. McClintock. Basically, if you make a large, heavy, spinning metal disk, switching on a strong magnetic field will make that disk dump its energy of rotation into a massive pulse of current. Such a device was built in the 1950s by Sir Mark Oliphant at Australian National University where it was used in synchrotron experiments until 1962. The remains of it. A magnetic moment is a quantity that represents the magnetic strength and orientation of a magnet or any other object that produces a magnetic field. More precisely, a magnetic moment refers to a magnetic dipole moment, the component of the magnetic moment that can be represented by a magnetic dipole. A magnetic dipole is a magnetic north pole.

A magnetic field line can never cross another field line. The magnetic field is unique at every point in space. Magnetic field lines are continuous and unbroken, forming closed loops. Magnetic field lines are defined to begin on the north pole of a magnet and terminate on the south pole. Key Terms. B-field: A synonym for the magnetic field. When the aluminum disk is placed near the magnet, the magnetic field exerts a force on the electrons in the aluminum. The magnetic force will cause the electrons to separate from the positively charged atomic nuclei. A portion of the disk will then become charged. Because the disk is spinning, the charges will move around the circumference of. Since any moving charge generates a magnetic field, one way of produc-ing a novel current is to take a uniform sphere of charge and set it spinning on its axis. To work out the field produced by such a sphere, we can start with the field generated by a spinning spherical shell of charge. The deriva.

A gyrocompass is a type of non-magnetic compass which is based on a fast-spinning disc and the rotation of the Earth to find. The magnetic field induced by the current that is induced, or that current that's being caused by the electromotive force and the magnitude of the force is going to be dependent on our resistance, that's going to go in the other direction, it's going to go down that way. Or it's going to induce a magnetic field that is gonna go downwards. This study explores the heat transfer characteristics of nanoliquid flowing over a rotating disk in the presence of the applied magnetic field and convective boundary condition.

The FC device, a type of spin-torque oscillator designed to maximize the FC effect, consists of two magnetic layers fabricated directly in the write gap of the write head. The two halves are placed together in fig 1b. When a magnetic field is applied (vertical field in fig 1b) and the two halves are spun together as a unit, the relative motion of the metal and the magnetic field should cause a radial voltage to appear, which causes the rim of the metal assembly to aquire a positive charge, and the axis of the assembly to receive an equal negative charge.

(A) Experimental set-up of a 3-mm-diameter graphite disk levitating on NdFeB magnets arranged to face in alternate directions. (B) A laser moves the disk in the direction of the light beam. As the aluminum disk spins through the magnetic field, eddy currents are induced within the disk, creating magnetic fields which oppose the relative motion of the disk to the magnets you are holding in position. This creates a braking force, slowing down the disk. There is a magnetic field generated in the wire due to the current. In the Earths core, the are vast amounts of iron moving around and spinning. This movement generates a current in the liquid metal. Because the core of the Earth is so large, the resulting magnetic field is very large also. Magnetic fields decrease in strength with distance.
