The silk makes the needle magnetic.

Construction of a magnetic compass Magnetic needle A magnetic rod is required when constructing a compass.

A magnetic needle is placed parallel with the copper strip.

This magnetised rod (or magnetic needle) is then placed on a low friction surface to allow it to freely pivot to align itself with the magnetic field.

The typical Chinese navigational compass was in the form of a magnetic needle floating in a bowl of water.

The true explanation was reserved for Faraday, namely, that electric currents are induced in the copper disc by the cutting of the magnetic lines of force of the needle, which currents in turn react on the needle.

For example, in 1819 Hans Christian Ørsted of Copenhagen discovered the deflecting effect of an electric current traversing a wire upon a suspended magnetic needle.

Needle bad.

A needle?

needle and thread.

As he was setting up his materials, he noticed a compass needle deflected from magnetic north when the electric current from the battery he was using was switched on and off.

Using a magnetic compass A magnetic compass points to magnetic north pole, which is approximately 1,000 miles from the true geographic North Pole.

Sami didn't know what Layla's needle contained.

This is how you hold the needle.

Nurse, please take this needle out, huh?

The interplanetary magnetic field is much stronger than the dipole component of the solar magnetic field.

Note Magnetic equator and northern and southern magnetic latitudes at 20 are shown by dashed lines.

Sami pulled a needle out of his pocket.

Normally now, I would take the needle out.

And the man said, I'm making a needle.
