Induction current is the electric current arising in a closed conductive loop when the flux of a magnetic induction penetrates this circuit [1] . The magnitude and direction of the induction current is determined by the law of electromagnetic induction and the Lenz rule . The induction current has the formula: Φ = Β * S * cos α , where Β is magnetic induction , S is the surface contour area, and α is the angle between the normal vector and the magnetic induction vector. [2]
Practical application
If you change the magnetic field near the fixed fixed conductor, then the cause of the induction current is a vortex electric field.
If you move a closed conductor near a stationary magnet, then the cause of the induction current is the Lorentz force.
Induction currents underlie the damaging effects of electromagnetic weapons .
