What rule determines the direction of the induction current?
| December 8, 2020 | education
The direction of the induction current in the circuit is determined by the Lenz rule:
The induction current is directed so as to counteract the change in the magnetic flux by which it is caused by its magnetic field.
ε = – ΔФ / Δt
Where
ε_i – current induction EMF
Ф – magnetic flux
t – time
Also the formula through the derivative:
ε = – Ф ‘
