Answer and Explanation:1 Magnetic field induction involves touching a magnet to a magnetic substance. The magnetic substance that is touched then becomes a magnet because the... Learn more about this topic: Magnetic Field | Overview & Ferromagnetic Materials ...
When this modulated electrical signal is applied to a coil, it produces an oscillating magnetic field, which causes the coil to move in and out over a magnetic core in that same pattern. The coil is then attached to a movable speaker cone so it can reproduce audible sound waves in the ai...
Alternating magnetic field generating induction coil is hollow and fluid cooled having longitudinal slits or conductors in axial terminal postdoi:DE19843087The induction heating unit has a hollow current carrying coil (5) with terminal connectors (3,4), in a mounting board (2), one of which (4...
Why same polarities of a magnet repels? What is the most important element for creating a magnetic field, and why? Why do magnetic monopoles not exist? Explain the difference between B and H in magnetism. Explain why magnetic monopoles do not exist. ...
The direction of the magnetic field depends on the direction of current flow, so an alternating current through the coil will result in a magnetic field changing in direction at the same rate as the frequency of the alternating current. 60Hz AC current will cause the magnetic field to switch ...
Induction uses the principle of magnetic induction to directly heat cookware, instead of using thermal conduction. Essentially, when you turn the cooktop on, an electric current flows through the copper coil under the glass surface, creating a magnetic field. ...
Electromagnetic induction is the magnetic field changes over time will inspire electric field, this electric field is called inductive electric field to distinguish it from Coulomb electric field, but 2 are both an electric field, the charge is. ...
Magnetic induction paint meters use a permanent magnet as the source of the magnetic field. A Hall-effect generator or magneto-resistor is used to sense the magnetic flux density at a pole of the magnet. Electromagnetic induction paint meters use an alternating magnetic field. A soft, ferromagnet...
It is found more convenient to adopt the point of view that a moving charge sets up a magnetic field, and this field exerts a force on another charge moving through it. 第 6、 8 章论述人们所说的电脑。 7、 Chapter 6, 7, and 8 deal with what is called the electronic brain. 学生们...
As previously mentioned, they generate a magnetic field. More specifically, magnetic sheet fanners induce a magnetic field of equal polarity onto the steel sheets that require separation. With the same polarity, a repelling force is created. When run through a magnetic sheet fanner, the steel ...
