The magnetic field generated by the electric current, around a straight wire, is related to the electric current and the distance “r” from the ... more
The Larmor formula is used to calculate the total power radiated by a non relativistic point charge as it accelerates or decelerates. This is used in the ... more
Counter-electromotive force (abbreviated counter EMF or simply CEMF), also known as back electromotive ... more
Electric generators induce an emf by rotating a coil in a magnetic field. Electromotive force, also called Emf, is the voltage developed by any source of ... more
If the magnetic field is uniform and all other forces are absent, then the Lorentz force will cause a particle to undergo a constant acceleration ... more
he decibel is a logarithmic unit used to express the ratio between two values of a physical quantity. The bel represents a ratio between two power ... more
An electromagnet is a type of magnet in which the magnetic field is produced by electric current. The magnetic field disappears when the current is turned ... more
Potential function for electrostatic forces between two bodies is the work required to move a charge from a point to any point in the electrostatic force ... more
