Simulating Induction Heating of Forging Billets

Induction is becoming an increasingly popular choice for heating steel billets prior to forging, due to its ability to create high heat-intensity quickly and within a billet, which leads to low process-cycle time (high productivity) with repeatable high quality, occupying minimal space on the shop floor.

Why Space Scientists Must Re

12-8-2017Then, the radiated magnetic field from the Sun (the solar wind if you prefer) increases in intensity via the normal electrical induction process so that it also becomes intense enough to stimulate the atoms of gases already in its path to a glowing, visible state of excitement.

Magnetic Field Lines

The magnetic field is an abstract entity that describes the influence of magnetic forces in a region. Magnetic field lines are a visual tool used to represent magnetic fields. They describe the direction of the magnetic force on a north monopole at any given position. Because monopoles are not found to exist in nature, we also discuss alternate means to describe the field lines in the sections

Eddy Current Testing: Basics

Their intensity depends on material properties, electromagnetic coupling (lift-off/fill-factor) and excitation frequency, but maximum on the surface These eddy currents also generate a secondary magnetic field, but in the opposite direction to the primary magnetic field

Use pole in a sentence

The magnetic potential at any point in a magnetic field is the work which would be done against the magnetic fdrees in bringing a unit pole to that point from the boundary of the field. 0 The potential due to a single pole of strength m at the distance r from the pole is V = m/ r, (7) the equipotential surfaces being spheres of which the pole is the centre and the lines of force radii.

Magnetic Induction

Magnetic induction in the Earth's crust is of scientific interest beyond space weather. It is a powerful tool for scientists studying the interior of the Earth. By measuring the natural variations of the geomagnetic and geoelectric fields (a technique known as magneto-telluric (MT) surveying (Simpson and Bahr, 2005)), they can infer information about the conductivity of subsurface layers and

Magnetic Flux Density Magnetic Induction Magnetic

In this case 'B' is perpendicular to the surface. (φ B) max = B A 1 = BA. Magnetic flux linked with a surface is maximum when area is held perpendicular to the direction of field. Since B = H. Here, is the permeability of the medium and 'H' is magnetic intensity, i.e., the number of lines of force per unit area in free space. (φ

3 Ways to Determine the Strength of Magnets

5-9-2019This has the highest magnetic flux density (12,800 gauss), coercive magnetic field strength (12,300 oersted), and overall energy density (40). It has the lowest maximum operating temperature and Curie temperature, at 150 degrees Celsius (302 degrees Fahrenheit) and 310 degrees Celsius (590 degrees Fahrenheit), respectively, and a temperature coefficient of -0.12.

Use induction in a sentence

Magnetic force has not merely the property of acting upon magnetic poles, it has the additional property of producing a phenomenon known as magnetic induction, or magnetic flux, a physical condition which is of the nature of a flow continuously circulating through the magnet and the space outside it.

Factors Affecting Inductance

15-7-2020There are four basic factors of inductor construction determining the amount of inductance created. These factors all dictate inductance by affecting how much magnetic field flux will develop for a given amount of magnetic field force (current through the inductor's wire coil):

What is Induction Heating and How do Induction Coils

Induction produces an electromagnetic field in a coil to transfer energy to a work piece to be heated. When the electrical current passes along a wire, a magnetic field is produced around that wire.
