GEN PHYSICS 2 - QUARTER 4

• Lenz's law


  Describes how an induced electric current always flows in a direction to oppose the change in magnetic field that produced it
• Lenz's law is nature's way of keeping a balance - if something tries to change the magnetic field in a circuit, the circuit will fight back
• Lenz's law is represented in Faraday's law of electromagnetic induction as a negative sign
• Φ


  Magnetic flux
• The negative sign in the formula represents Lenz's Law - it shows that the induced EMF and the change in flux have opposite signs
