The two laws of electromagnetic induction
WebElectromagnetic Induction 227 SUMMARY 1. The magnetic flux through a surface of area A placed in a uniform magnetic field B is defined as, Φ B = B. A = BA cos θ where θ is the angle between B and A. 2. Faraday’s laws of induction imply that the emf induced in a coil of N turns is directly related to the rate of change of flux through it, B d d N t Φ ε = - Here Φ Β is … WebFeb 20, 2024 · Figure 23.5. 1: (a) When this bar magnet is thrust into the coil, the strength of the magnetic field increases in the coil. The current induced in the coil creates another field, in the opposite direction of the bar magnet’s to oppose the increase. This is one aspect of Lenz's law--induction opposes any charge in flux.
