Explain Faradays law of electromagnetic induction. |
| Answer» Faraday\'s Law of electromagnetic inductionThe emf,E , produced around a loop of conductor is proportional to the rate of change of the magnetic flux, φ, through the area, A, of the loop. This can be stated mathematically as:where ϕ=B⋅Aand B is the strength of the magnetic field. N is the number of circuit loops. A magnetic field is measured in units of teslas (T). The minus sign indicates direction and that the induced emf tends to oppose the change in the magnetic flux. The minus sign can be ignored when calculating magnitudes.\xa0\xa0\xa0 | |
