Class 12 Physics simulations · Electromagnetic Induction

Mutual induction between coils

Drive a changing current in one coil and measure the emf induced in its neighbour.

Open the simulation

What to notice

Only a changing primary current induces a secondary emf.

Key relation

ε₂ = −M dI₁/dt

Try this

Reverse the current ramp and watch the induced polarity reverse.

What you can change

• Mutual inductance: 1 to 100 mH
• Primary current rate: -50 to 50 A/s
