Magnetic Field Magnetic Flux and Electric Motor

Magnetic fluxe total number of magnetic field lines penetrating any surface play please perpendicular to the magnetic field is known as magnetic flux it is generated by pi

Magnetic flux density the ratio of the magnetic fluxe in plane perpendicular to the field and the area of plane is called as magnetic density it is denoted by b magnetic fluid density b is equal to magnetic flux by area is equals to pi by a is equals to equal to be

Electric motor it is a device which Converse electrical energy into a mechanical energy

Slip rings are slip ring is an electro mechanical device that faciliates transmission of electrical power and signals from a stationary system to a rotating system


Induced current produce in a conductor due to change in magnetic field through the region is called as in use current induce EMF it is defined as the generally turn of potential difference in a coil of due to the change and the magnetic flux through it or EMF is induced in the coil when a magnet is full in an out of it electric generator and electric generator is an electric electronic appliance that converts mechanical energy into electrical energy


AC and DC current alternating current AC is an electric current that periodical rewards its direction where as direct current DC flow only in single direction which cannot be changed periodically RMS value the MS values the square root of arithmetic mean of a square of the values of the square of the functions that defines the continuous way form

Physical size zero by root 2 and RMS is equal to 20 by root 2 here i 0 0 the peak value of AC current and ac EMF
