Class 12 Physics simulations · Moving Charges and Magnetism

Magnetic field inside a solenoid

Change the coil density and current to control the internal magnetic field.

Open the simulation

What to notice

More turns per unit length produce a stronger field for the same current.

Key relation

B ≈ μ₀NI/L

Try this

Double the coil length at fixed turns and current.

What you can change

• Number of turns: 200 to 1000
• Coil length: 0.2 to 1 m
• Current: 0.5 to 5 A
