NettetThus, the rate of change of flux ΦB will induce an emf, which is given by: ϵ = − d ϕ B d t = − d d t ( B l x) = − B l d x d t = B l v. Where, the speed of conductor (PQ), v = -dx/dt and is the formula of induced emf. This induced emf due to the motion of an electric conductor in the presence of the magnetic field is called motional emf. http://physics.bu.edu/~duffy/sc545_notes02/motional_emf.html Nettet5. nov. 2024 · Motion of a bar on two parallel rails Consider a U-shaped rail in a uniform magnetic field on top of which a bar can slide with no friction, as illustrated in Figure … can tb be spread by shaking hands

NettetSo here it is. So let's list down some more important properties of these magnetic field lines. The first property is that the lines start from the north and end into the south. But this is outside the bar magnet. If we're to peak inside the magnet, then you see the lines run south to north. Closing the entire loop.

NettetFind out how an electromagnet uses an electrical current to generate a magnetic field with this guide for KS3 physics students aged 11-14 from BBC Bitesize. NettetA magnetic field is basically used to describe the distribution of magnetic force around a magnetic object. Magnetic fields are created or produced when the electric charge/current moves within the vicinity of the magnet. Here, the sub-atomic particle such as electrons with a negative charge moves around creating a magnetic field.
