ผู้ทดลองขับเคลื่อนแม่เหล็ก　B10-3288

The ring-shaped ferrite magnets are inserted into the struts, and the magnets are observed to rebound and rise.
You can also experiment by removing the strut from the base and laying it on its side.

Easy to use and beautiful curves are made by cutting 0.3 mm diameter galvanized iron wire to 2~5 mm length. This short iron wire is used for magnetic field observation instead of iron powder.
Because it is linear, you can observe a beautiful curve.

It is a set of a mug tip and a transparent styrene case.
You can observe a magnetic field inside the transparent styrene case by placing a small amount of a mug tip in the case, applying a magnet from the outside of the case, and shaking the case several times.

A linear iron powder and silicon oil are enclosed in the laboratory. By inserting a magnet into the center, three-dimensional magnetic field lines can be observed.
With the use of linear iron powder, the connection between iron powders is good, and the magnetic field lines appear beautifully.

An arnico magnet is attached to the tip of a metal bar (brass) in the shape of a freely rotating compass.
It is possible to confirm the appearance of a magnetic field such as a bar magnet in three dimensions.

When you apply a magnet to a green card, it changes to black and a pattern corresponding to the magnetic field appears.
The pattern remains as it is when the magnet is moved away, but changes depending on the magnetic field when the magnet is applied again.
