You’re walking on the ground…
but beneath your feet, something invisible is happening. ⚡

High-voltage power cables can be buried underground,
completely hidden from your eyes…

Yet they still create a magnetic field around them.

The reason is simple —
electric current creates magnetism.

When alternating current flows through the cables,
it produces a changing magnetic field around the conductors.

And here’s the interesting part…

The ground can hide the cables,
but it doesn’t simply block their magnetic field.

Engineers arrange the cables very close together,
which allows their magnetic fields to partially cancel each other.

That makes the field fall off rapidly as you move away from the cable.

So even though the electricity is completely invisible,
its presence can still extend into the space around us.

You can’t see the current.
You can’t hear the magnetic field.

But the physics is there…
right beneath your feet. ⚡
