Class 12 Physics simulations · Moving Charges and Magnetism

Force between parallel currents

Reverse one current and see the wires attract or repel.

Open the simulation

What to notice

Currents in the same direction attract; opposite currents repel.

Key relation

F/L = μ₀I₁I₂/(2πd)

Try this

Reverse the second current.

What you can change

• Current 1: 1 to 15 A
• Current 2: -15 to 15 A
• Wire spacing: 0.1 to 0.5 m
