Magnetic induction equation
WebFormula of Magnetic induction φ = NAB cosθ Where A = Area of the coil B = Magnetic induction field φ= Magnetic flux through the coil θ= angle between the unit vector and magnetic filed N = number of turns in the coil ε = -d/dt (NAB cosθ) ε = Induced emf. Nφ = number of turns: φ = magnetic flux L= coefficient of self induction. i = current WebAccording to Lenz’s law, the emf produced in the coil will drive a current in the direction that creates a magnetic field B → coil = B coil ( − x ^) inside the coil pointing to the left. This will counter the increase in magnetic …
