Physics, Chapter 5 (5.4 Induced Emf)

What’s Induced EMF

Current generated when an object pass thru a magnet and cutting their magnetic field

Formula for Induced emf

What’s Lenz’s Law

If Magnetic flux goes right, Induced emf goes left and vice versa

How to determine the direction of Induced Current in Coil & Solenoid

Right Hand Grip Rule : Thumb = Induced Current, Other finger = Current

How to determine the direction of Induced Current in Straight Conductor (Wire)

Right Hand Palm Rule : Thumb = Direction of object going, Finger = Direction of B, Palm = Direction of Induced Current

Formula for Induced emf in straight conductor (Wire)

Theta = Degree between B and V

Formula for Induced emf in Coil if Area is constant

Formula for Induced emf in Coil if Magnetic Flux is constant

What’s the tips for Induced emf

Use V = Epsilon = IR
