Which factors affect magnetic force? Does the magnetic force obey Newton's third law? What creates a magnetic field? What does the magnetism in an MRI help accomplish? What does the magnetic field around a solenoid look like? Is magnetism the strong nuclear force?
When electric current flows in a conductor, it creates a magnetic field. In the case of alternating current the magnetic field varies with that current. This magnetic field affects adjacent conductors in two ways: the first is to induce eddy currents, and the second is to induce an electromagn...
Lenz law states that the direction of the induced current in a conductor creates a magnetic field such that the direction of the magnetic field is... Learn more about this topic: Magnetic Flux Equation, Motional EMF & Lenz's Law Equation ...
The voltage creates a magnetic field around it. The current creates an electrostatic field around it. Dimensions of voltage is Dimensions of current is In the hydraulic analogy, electric potential or voltage is equivalent to hydraulic water pressure. In the hydraulic analogy, electric current is ...
When a voltage is applied across the terminals of an inductor, the current flowing creates a magnetic field. This magnetic field again creates an induced current in the inductor of opposite polarity, according to Lenz’s law. The currents do not cancel each other out – rather, the induced ...
Metals can be magnetic and non-magnetic. The magnetic ones will produce a field around them, usually described as “ferromagnetic.” These metals are not magnetic by themselves in their natural state. Still, they can be attracted to objects that produce magnetic fields. ...
DC Motor Definition: A DC motor is defined as a device that converts DC electrical energy into mechanical energy. Principle of Operation: It operates on the principle that a current-carrying conductor in a magnetic field experiences a force, producing motion. ...
A testing device used to detect the presence of voltage in a wire or piece of equipment without making direct contact with the conductor or the energized partDC - Direct currentAn electric current that flows in one direction only (see “alternating current” (AC))DUT – Device under testThe...
Inductance is defined as the property of an electric conductor which causes an electromotive force that is generated due to a change in the current flow. There are two types of inductance: self-inductance and mutual inductance.
Electromagnetic induction is the creation ofcurrent in a conductoras it travels within a magnetic field. A magnet generates lines of magnetic force and iron filings will align themselves along these invisible lines of flux. According to Faraday's Law ofInduction, if you move a wire back and for...
